When Polyester Took Over Fashion
Polyester has a reputation problem. Mention silk and we think of luxury; cashmere brings softness to mind, while linen conjures summer dresses and that particular sort of elegant crumpling we have somehow agreed is part of its charm. Polyester is rather more likely to inspire memories of static, questionable shirts and something your grandmother wore in 1974 that appeared capable of surviving a small explosion. Yet dismissing polyester as the slightly embarrassing fabric of the 1970s means overlooking one of the biggest changes in twentieth-century fashion.
There was a time when synthetic fibres represented the future. Clothes that resisted creasing, held their shape, dried quickly and demanded less ironing were not regarded as an inferior substitute for the real thing; they were modern, practical and exciting. By the 1960s and 1970s, polyester had become part of a much wider transformation in the way clothing was manufactured, sold, cared for and worn. Fashion could be colourful, affordable, easy to maintain and increasingly fast-moving, and synthetic fibres helped to make that possible.
So how did a textile once promoted as a modern miracle become one of fashion's favourite punchlines? As is so often the case with vintage fashion, the real story is far more interesting than the stereotype.
What Exactly Is Polyester?
Although we casually talk about polyester as though it were one particular fabric, the term actually describes a family of synthetic polymers. The polyester that became enormously important to the clothing industry is predominantly polyethylene terephthalate, better known as PET, which can be spun into fibres and manufactured into an extraordinary variety of textiles.
This is one reason why judging a vintage garment simply because its label says “100% polyester” can be so misleading. Polyester can be fine and sheer, soft and flowing, densely knitted, heavily textured, crisp or surprisingly silky. Two garments carrying exactly the same fibre content can feel so different that, without their labels, you might never imagine they were made from the same basic type of fibre.
The development of polyester belonged to a much wider twentieth-century fascination with man-made materials. Rayon had already demonstrated that textile fibres did not necessarily have to arrive directly from sheep, cotton plants or silkworms, although rayon is made from regenerated cellulose rather than being fully synthetic. By the 1930s, European and American companies were investing heavily in synthetic-fibre research, and fashion was gradually entering an age in which scientists could increasingly engineer textiles to possess particular qualities rather than simply working with whatever nature provided.
Before Polyester, There Was a Textile Revolution
The idea of creating clothing fibres in a laboratory made perfect sense in a century obsessed with technological progress. Cars, household appliances, plastics, aviation and communications were transforming everyday life, so why should the contents of the wardrobe remain untouched? Textile manufacturers began developing fibres intended to be stronger, more consistent, easier to care for and capable of performing in ways traditional materials could not always match.
An important breakthrough came in Britain during the early 1940s, when chemists John Rex Whinfield and James Tennant Dickson developed the polyester fibre that would become associated with the name Terylene. DuPont later developed polyester commercially in the United States under the Dacron name, and by the early 1950s polyester was beginning to reach consumers in clothing. Early promotion concentrated heavily on qualities such as crease resistance, durability and ease of care.
Those claims can sound rather ordinary now because we have grown accustomed to throwing clothes into a washing machine and expecting them to emerge ready for another outing. In the post-war household, however, the amount of time spent washing, drying and pressing clothing could be considerable. A garment that kept its shape, resisted wrinkles and reduced the ironing pile was not merely a scientific curiosity; it offered a genuine practical advantage.
The 1950s Discover the Easy-Care Wardrobe
Polyester did not suddenly materialise in 1970 accompanied by flared trousers and a shirt collar large enough to achieve flight. By the 1950s, synthetic fibres were already finding an enthusiastic audience, and they fitted neatly into the optimism surrounding new technology and consumer goods. Ready-to-wear clothing was expanding, living standards were changing and manufacturers were increasingly selling the idea that science could make everyday life easier.[
The fashion industry was equally interested. Synthetic fibres appeared at different levels of the market, from practical everyday clothing to designer fashion, while blends allowed manufacturers to combine traditional fibres with some of the properties offered by the new synthetics. Wool blended with polyester, for example, could retain much of the character of wool while gaining additional resistance to creasing and wear.
There was also an important psychological shift taking place. Newness itself had become desirable. We now tend to romanticise natural materials when looking back at vintage fashion, but mid-century consumers were not necessarily yearning for an imaginary past filled with pure wool and silk. For many, a fabric developed using the latest technology represented progress. “Man-made” could be a selling point rather than an apology.
Why the 1960s Fell for Synthetic Fabrics
If ever a decade was ready to embrace clothes made from futuristic materials, it was the 1960s. Fashion became increasingly youthful and experimental, designers played with plastics, PVC and synthetics, and the Space Age made materials that might once have appeared strange seem perfectly suited to a world dreaming about the future. André Courrèges, Pierre Cardin and other designers associated with futuristic fashion helped create an atmosphere in which innovation in material and construction felt every bit as important as traditional luxury.
At the same time, fashion was becoming more democratic. The growth of ready-to-wear clothing and youth-orientated boutiques meant that trends could spread quickly, while synthetic fibres offered manufacturers enormous freedom. They could produce colourful, relatively affordable clothing in fabrics that were easy to maintain and capable of holding the crisp shapes, permanent pleats and bold silhouettes increasingly appearing in fashionable wardrobes.
Colour was another major attraction. Polyester could take brilliantly saturated shades, and this became particularly important as fashion moved away from the more restrained palettes associated with earlier periods. Strong oranges, acidic greens, purples, turquoise, shocking pink and sunshine yellow found an enthusiastic home in synthetic textiles, while improvements in printing allowed equally exuberant patterns to cover them.
For anyone who handles vintage clothing regularly, this is one of polyester's most impressive legacies. We still encounter late 1960s and 1970s garments whose colours are astonishingly vivid more than half a century later. The prints can look almost indecently cheerful after decades in a wardrobe, as though nobody remembered to tell them they were supposed to age.
The 1970s: Peak Polyester
By the 1970s, polyester was everywhere. The decade has even been described by fashion historians as the “Polyester Decade”, and it is easy to understand why. Synthetic textiles appeared across women's, men's and children's clothing, from everyday separates to eveningwear, and their versatility suited a decade in which fashion itself was extraordinarily varied.
For women, polyester appeared in blouses, jersey dresses, maxi dresses, trouser suits, skirts, eveningwear and countless printed day dresses. Menswear embraced it with particular enthusiasm in shirts, trousers and the notorious leisure suit, while children's clothing followed many of the same trends in colourful easy-care fabrics. The enormous variety is sometimes lost when we reduce 1970s polyester to a few comedy stereotypes.
The fabric itself was equally varied. A fine polyester chiffon could create a light, fluid evening garment, while double-knit polyester produced something altogether more substantial. Designer Stephen Burrows used polyester chiffon in his colourful early 1970s eveningwear, demonstrating just how far the material could travel from the cheap, stiff synthetics that would later dominate its reputation. Polyester was not a quality grade; it was a fibre, and what happened to it depended enormously on how it was manufactured and how skilfully it was used.
Print was perhaps where the decade really allowed polyester to show off. Florals became enormous, geometrics grew bolder, abstract patterns twisted across dresses and shirts, and psychedelic influences from the late 1960s continued into the new decade. Many garments were relatively simple in construction because the fabric itself supplied the drama. When the print is a riot of orange, purple, lime and turquoise swirls, it hardly needs much assistance.
Crimplene, Terylene and Those Vintage Clothing Labels
Spend enough time looking through vintage clothing labels and you will eventually encounter names that sound wonderfully futuristic: Terylene, Dacron and Crimplene among them. They are sometimes treated today as though they were completely separate mystery fibres, or used interchangeably as general words for vintage polyester, but the reality is more specific.
Terylene became an important British trade name for polyester fibre, while Dacron performed a similar role in the United States. Crimplene, meanwhile, became associated with a particular type of textured polyester yarn and fabric and is one of the names most strongly linked with British 1960s and 1970s clothing. Its resilience, crease resistance and ability to hold its shape made it ideally suited to the easy-care wardrobe.
The reputation of Crimplene today tends to depend rather heavily on whether you have actually worn it. Some examples are soft, comfortable and beautifully structured; others possess enough substance to make you wonder whether the dress might remain standing after you have taken it off. That variety is precisely why it is unwise to use “Crimplene” as a catch-all term for every vintage polyester garment with a slightly textured surface.
These old fibre names are fascinating clues when they appear on vintage labels, but they should not be treated as automatic dating devices. Trademarked fibres could remain in use for considerable periods, and the garment as a whole — its construction, styling, label, manufacturer and provenance — always tells us more than one word on a fibre label can manage alone.
Why Was Polyester So Popular?
Looking back from an era in which polyester is frequently criticised, it can be tempting to wonder why consumers embraced it so enthusiastically. The answer is actually very straightforward: it solved problems. Many polyester garments resisted creasing, dried relatively quickly, held their shape and could be washed without the complicated care demanded by some traditional fabrics. For households increasingly equipped with washing machines and for women whose lives were changing rapidly outside the home as well as within it, easy-care clothing had an obvious appeal.
Polyester was also tremendously versatile. Manufacturers could create lightweight sheers, smooth jerseys, sturdy double knits and countless blends, allowing the fibre to appear in almost every part of the wardrobe. Permanent pleats and other heat-set effects could survive repeated wear, while strong colours and prints remained attractive. Fashionable clothing could be produced at a wide range of price points without relying on expensive silk or fine wool.
None of this means every polyester garment was wonderful. It simply means that the polyester boom was not the result of an entire generation temporarily misplacing its good taste. Consumers had very practical reasons for buying it, and manufacturers had equally practical reasons for making it.
When Polyester Became a Fashion Punchline
The trouble for polyester was that enormous success eventually worked against it. As synthetic clothing flooded the market, quality varied dramatically. Alongside good fabrics came cheap examples that were stiff, shiny, prone to static and distinctly unpleasant in warm weather. Poor breathability became a particular complaint, while mass production meant polyester increasingly became associated with inexpensive clothing rather than exciting textile innovation.
Fashion did the fibre few favours either. Some of the most easily caricatured looks of the 1970s relied heavily on synthetics, and the polyester leisure suit has enjoyed a particularly unforgiving afterlife. As tastes changed towards the end of the decade and into the 1980s, the word “polyester” increasingly carried connotations of cheapness and artificiality, while natural fibres regained a certain cachet.
It is one of fashion history's more entertaining reversals. A material that had been marketed as an exciting technological improvement became something manufacturers sometimes seemed almost embarrassed to mention. The joke proved remarkably durable too; even today, some shoppers will recoil instinctively from a polyester label before they have so much as touched the garment.
Was Vintage Polyester Really That Bad?
After more than twenty years of handling vintage clothing, I would love to tell you that polyester has been unfairly maligned and every vintage example is secretly magnificent. Unfortunately, some of it really is horrible. There are vintage polyester fabrics that feel beautiful, and there are others that feel rather like something originally intended to cover garden furniture. Pretending otherwise would do nobody any favours.
What experience does teach you is just how enormous the variation can be. Good vintage polyester can have a lovely weight and drape, particularly in jersey dresses and better-quality printed garments. Fine examples can be surprisingly soft and fluid, while more substantial textiles can give structure to a garment in exactly the way its design requires. Even the heavier fabrics have their place when the cut and construction work with them rather than against them.
Then there is the colour. This is one area in which vintage polyester can be genuinely spectacular. We regularly see pieces from the 1960s and 1970s with remarkably vibrant prints that have retained their intensity for decades. Florals, geometrics and abstract patterns can still look wonderfully fresh, and sometimes the fabric is the entire reason a garment stops you in your tracks.
The disadvantages are equally real. Dense polyester can feel hot, static can be irritating and some fabrics snag or pull. Personal preference matters enormously too. Someone who cannot bear the feel of a substantial double knit may happily wear a lightweight polyester chiffon without giving the fibre content a second thought. The fairest verdict is therefore not that vintage polyester was good or bad, but that the quality of the textile and the garment mattered far more than the fibre name alone.
Why Has So Much Vintage Polyester Survived?
One of the great ironies of polyester's supposedly inferior reputation is that the stuff can be extraordinarily determined to live forever. Delicate natural-fibre garments of the same age may have suffered from moth damage, staining, fibre deterioration or simply decades of wear, while a wildly patterned polyester dress can emerge from the back of a wardrobe looking ready to attend another party.
That durability has preserved an enormous amount of everyday fashion history. Museums and fashion books naturally gravitate towards exceptional couture and designer pieces, but ordinary clothing tells us just as much about what people actually wore. The polyester dresses, shirts, blouses and trousers surviving in wardrobes, charity shops and vintage collections preserve the colours, prints and silhouettes that were part of daily life for millions of people.
It also helps explain why polyester remains such a familiar sight in the vintage trade. Age alone does not necessarily make these garments fragile, although every piece still needs to be judged individually for condition. When a fifty-year-old dress remains colourful, structurally sound and perfectly wearable, it becomes rather difficult not to respect the material at least a little.
Polyester Never Actually Went Away
Perhaps the most interesting twist in the story is that polyester never really disappeared. It remains one of the most important fibres in modern clothing, appearing in sportswear, fleece, linings, dresses, outerwear, technical clothing and countless blended fabrics. Textile technology has moved far beyond many of the heavy synthetics that shaped polyester's reputation, and modern polyester can be engineered into fine microfibres and performance textiles that would bear little resemblance to a 1970s double-knit trouser suit.
Its environmental impact, however, has become an increasingly important part of the conversation. Conventional polyester is made from fossil-fuel-derived raw materials, it does not biodegrade in the same way as natural fibres, and synthetic textiles can release microfibres during washing. None of that should be brushed aside simply because we happen to love vintage clothing.
There is, however, an important distinction between producing another new polyester garment and continuing to use one that already exists. The environmental cost of manufacturing a dress in 1972 occurred decades ago, and keeping that garment wearable today is not the same thing as demanding the production of a replacement. That does not magically turn vintage polyester into an environmentally perfect fibre, but it does demonstrate something increasingly valuable: longevity. A garment capable of surviving and remaining useful for fifty years sits rather awkwardly beside a modern culture in which clothing can be bought cheaply, worn briefly and discarded.
What Should You Look for When Buying Vintage Polyester?
The best advice is to judge the garment before judging the fibre. Look at the print, construction, cut, condition and, most importantly, whether you actually like it. A fabulous 1970s maxi dress does not become less fabulous simply because its label confirms that it is polyester, just as a poorly made garment does not become wonderful because it happens to be silk.
Feel the fabric whenever possible because vintage polyester varies enormously in texture and weight. Check carefully for pulls and snags, particularly on smoother jerseys, and inspect seams and stress points just as you would on any older garment. Staining can occasionally prove stubborn, while permanent pleats and textured surfaces should still appear even and intentional.
It is also worth remembering that durability does not mean invincibility. Trims, linings, zips, elastic and stitching may age differently from the polyester itself, so the main fabric can look almost immaculate while another component requires attention. Vintage clothing is always best assessed as a complete object rather than by one material alone.
Above all, don't let an old prejudice make the decision for you. If a polyester garment has already spent half a century proving that it can survive, still looks fantastic and makes you want to wear it, the fibre has probably earned the right to be judged on its own merits.
Is Vintage Polyester Breathable?
Polyester generally absorbs less moisture than fibres such as cotton and can feel less breathable, particularly when it is densely constructed. The comfort of an individual vintage garment nevertheless depends on much more than fibre content, including the weight and construction of the fabric, whether it is lined and how closely the garment fits. A lightweight polyester chiffon and a substantial double-knit dress may both say polyester on the label while feeling completely different to wear.
Can You Wash Vintage Polyester?
Many polyester garments were originally sold precisely because they were easy to care for, but a fifty-year-old garment should not automatically be treated exactly as it was when new. Always consider its current condition, construction, trims, lining and any surviving care instructions before washing. The polyester itself may be robust while an old zip, decorative trim, interfacing or stitching requires rather more sympathy.
How Can You Tell If Vintage Fabric Is Polyester?
A surviving fibre-content label is the best evidence. Without one, experienced handling can certainly provide clues, but appearance and feel alone are not infallible because polyester has been manufactured in an enormous range of textures and has frequently been blended with other fibres. As with so many aspects of vintage identification, several pieces of evidence are more useful than one supposedly foolproof test.
Is Crimplene the Same as Polyester?
Crimplene is a name associated with polyester, but the two words are not simply interchangeable. Crimplene was a trademarked textured polyester yarn and fabric that became particularly familiar in British mid-century clothing. It is therefore perfectly reasonable to describe genuine Crimplene as polyester, but not every vintage polyester garment is Crimplene.
When Was Polyester Most Popular in Fashion?
Polyester became commercially important during the 1950s and grew increasingly common throughout the 1960s, but its cultural association with fashion is strongest during the 1970s. By then synthetic textiles were appearing across virtually every area of the wardrobe and at many different levels of the fashion market, which is why the decade remains so closely associated with polyester today.
The Fabric That Refused to Disappear
Polyester's journey from scientific innovation to modern miracle, mass-market favourite and eventual fashion joke tells us far more than the history of a single fibre. It reflects a profound change in what twentieth-century consumers expected from their clothes. Fashion increasingly needed to be practical as well as attractive, easy to care for as well as affordable, and capable of keeping pace with lifestyles that were changing just as rapidly as the clothes themselves.
Polyester helped create that wardrobe, sometimes beautifully and sometimes spectacularly badly. The best vintage examples remind us what the material could achieve: extraordinary prints, saturated colours, strong silhouettes and garments durable enough to reach the twenty-first century still perfectly capable of being worn. It may never inspire quite the romance of silk or the prestige of cashmere, but perhaps polyester has the last laugh. While everybody was busy making jokes about it, the fabric simply carried on surviving.
