Vintage Size Conversion: Your Ultimate Guide to the Perfect Fit

Writer: Emma (My Vintage)Emma (My Vintage)

Finding the perfect fit in vintage clothing can sometimes feel like solving a complex puzzle. With sizing standards changing dramatically over the decades and variations between different manufacturers, what might be labelled as a size 12 from the 1960s could be worlds apart from today's size 12. But fear not! We at My Vintage have created this comprehensive guide to help you navigate the wonderful world of vintage sizing with confidence.



Why Vintage Sizes Are Different


Before we dive into the nitty-gritty of measurements, it's important to understand why vintage sizes differ so significantly from modern ones. In the mid-20th century, sizing was based on different standards, and over time, manufacturers have adjusted their sizing to accommodate changing body shapes and, yes, a touch of vanity sizing.


For instance, a 1960s size 12 would typically be equivalent to a modern UK size 8. This isn't because people were necessarily smaller back then, but rather because the sizing system itself was different.


Key Factors Affecting Vintage Sizing:

  • Era of manufacture

  • Country of origin

  • Intended garment fit

  • Fabric type and construction

  • Manufacturing standards of the time


Measuring Yourself Correctly

Before shopping for vintage clothing, having your current measurements is essential. Here's how to measure yourself accurately:


Bust: Measure around the fullest part of your bust while wearing a well-fitting bra

Waist: Measure around your natural waistline (typically the smallest part)

Hips: Measure around the fullest part of your hips

Shoulder width: Measure from shoulder point to shoulder point across your back

Arm length: Measure from shoulder point to wrist


Pro tip: Always use a soft measuring tape and don't pull it too tight. Stand naturally and have someone help you if possible.


Understanding Measurements vs. Size Labels


Rather than relying on potentially misleading decade-specific size conversions, the most reliable way to ensure a perfect vintage fit is to focus on actual garment measurements. Here's why:


Garment Measurements Matter Most


Every vintage piece should be considered unique when it comes to sizing. Instead of trying to correlate modern sizes with vintage ones, we recommend:

  • Always checking measurements of garments

  • Comparing these to your own measurements

  • Allowing 1-2 inches of ease for comfort (depending on the style and intended fit)

  • Understanding that measurements are more reliable than any size label


Essential Measurements to Know

When shopping vintage, these are the crucial measurements to consider:


For Dresses and Tops:

  • Bust (measured flat across at fullest point, then doubled)

  • Waist (measured flat across at smallest point, then doubled)

  • Shoulders (measured seam to seam across back)

  • Length (from shoulder to hem)

  • Sleeve length (from shoulder seam to cuff)


For Skirts and Trousers:

  • Waist (measured flat across, then doubled)

  • Hips (measured flat across at fullest point, then doubled)

  • Length (from waist to hem)

  • Inseam/Inside Leg (for trousers)

  • Rise (for trousers, from crotch seam to waist)


How My Vintage Ensures Accurate Measurements


At My Vintage, we understand that accurate measurements are crucial for a successful vintage purchase. That's why we've developed a thorough measuring process for every garment that enters our collection.



Our Measuring Process

Each piece is carefully measured while laid flat on a clean, flat surface. We take multiple measurements to ensure accuracy and always measure twice to confirm our findings. All measurements are recorded in both inches and centimetres for our international customers.


For each garment, we measure: • Every crucial dimension as detailed above • Any unique features that might affect fit • Additional measurements specific to the garment type • Any areas of potential alteration or concern.


On our website you'll find: • Clear, detailed measurements for each garment • Photos showing the specifics of each piece • Notes about fabric flexibility or restriction • Information about closures (zips, buttons, etc.) • Any relevant details about the garment's construction


Modern Size Approximation

To help our customers, we provide an approximate modern UK size range for each garment based on its measurements. However, we always encourage customers to focus primarily on the actual measurements and compare these with their own measurements.


For example, we might list a 1960s dress as:

Measurements:

Bust: 36 inches

Waist: 28 inches

Hips: 38 inches

Length: 40 inches

Approximate modern size: UK 10-12


This detailed approach helps our customers to make informed purchasing decisions, reduce the likelihood of returns, feel more confident about buying vintage online and understand exactly how a garment might fit. Also, our team is always available to offer their help for instance, provide additional measurements if needed, advise on fit and styling, discuss potential alterations or help you find the perfect piece in your size.


Understanding Ease and Fit

Different eras and styles require different amounts of ease:

  • 1950s wiggle dresses: minimal ease for a fitted look

  • 1950s full skirts: significant ease in the hip area

  • 1960s shift dresses: straight cut with moderate ease

  • 1970s maxi dresses: often flowing with generous ease

  • 1940s tailored jackets: structured with room for layers


Understanding Label Terminology

Different decades used various sizing systems. Here's what they mean:


  • W followed by a number: Refers to waist measurement in inches

  • B followed by a number: Refers to bust measurement in inches

  • Numbers only (e.g., 12, 14): Standard dress size for the era

  • S, M, L: Became more common in later decades

  • Continental sizes: Often found in European vintage pieces


Tips for The Perfect Vintage Fit


1. Always Check Measurements

Never rely solely on the size label. Always check the actual measurements of the garment against your own measurements or those of similar garments that fit you well.


2. Consider the Intended Fit

Different decades had different ideals for how clothing should fit. For example, a 1950s dress was meant to be worn with specific undergarments, while 1970s pieces often had a more relaxed fit.


3. Allow for Alterations

When buying vintage, consider leaving room for alterations. It's often easier to take in a garment than let it out so if something is a little too big then you can have it expertly tailored to fit you at a relatively low cost.


4. Fabric Behaviours

  • Cotton may shrink slightly

  • Elastane content means a little stretch

  • Wool can be more forgiving depending on the piece

  • Synthetic fabrics tend to hold their shape

  • Silk requires careful handling


Common Fit Issues and Solutions


Waist Too Small

Solution: A skilled tailor can often let out the waist slightly (1-2 inches maximum) if there's enough seam allowance.


Shoulders Too Narrow

Solution: This is one of the hardest alterations to make. Consider padding instead, or look for a different piece.


Length Adjustments

Solution: Hemming is usually straightforward, but check for proper proportions first.


Bust Too Tight/Loose

Solution: Darts can often be adjusted, but major changes may affect the garment's overall look.


Care and Storage Tips for Maintaining Fit

  • Store items on appropriate hangers

  • Use padded hangers for delicate pieces

  • Keep knits folded to maintain shape

  • Allow space between garments

  • Use appropriate cleaning methods to prevent shrinkage



Special Considerations


Undergarments

The right undergarments can make a significant difference in how vintage clothing fits. Consider:

  • Period-appropriate bras

  • Shapewear if desired

  • Slip dresses for proper draping


Modern Body Shapes

Remember that body shapes and proportions have changed over time. You might need to:

  • Mix sizes between top and bottom

  • Make strategic alterations

  • Choose styles that work for your body type


Size Up If

  • The garment is made from non-stretch fabric

  • You're between sizes

  • The item is from the 1950s or earlier

  • You're unsure about shrinkage


Size Down If

  • The fabric has some stretch

  • The style is meant to be fitted

  • The garment appears to have stretched over time

  • You're planning alterations


Final Tips for Success


1. Don't get discouraged if something doesn't fit perfectly right away

2. Build relationships with reliable sellers who provide accurate measurements

3. Keep detailed notes of what sizes work for you in different eras

4. Remember that alterations can be your best friend

5. Focus on how garments fit rather than the size on the label


Understanding vintage sizing might seem daunting at first, but with these guidelines and a bit of practice, you'll be navigating the vintage fashion world like a pro. Remember, the joy of vintage shopping lies in finding unique pieces that make you feel fantastic – regardless of the number on the label.
