Women's Vintage Clothing Sizing Guide
Understanding Vintage Sizing
Vintage clothing was made before modern sizing was standardized, which means a vintage size 14 is not the same as a modern size 14. As a general rule, vintage sizes run 4–6 sizes smaller than today's sizing. This guide will help you navigate sizing by decade so you can shop with confidence.
The Golden Rule: Always measure the garment, not the tag.
Sizing by Decade
1930s & 1940s Sizing in this era was based on bust measurement only. A size 14 typically indicates a 34" bust. Waists were extremely fitted — often 24–26" — reflecting the hourglass silhouette of the era. Expect very structured construction with little ease.
1950s The full hourglass silhouette dominated. Sizing remained bust-based but waist suppression was extreme. A vintage 1950s size 14 typically corresponds to a modern size 6–8. Look for boning, structured bodices, and full skirts with limited stretch.
1960s Sizing began to shift toward a more relaxed, mod silhouette. Waist ease increased slightly. A 1960s size 14 typically corresponds to a modern size 8–10. Shift dresses and A-line styles offer more room through the hip.
1970s Sizing became more varied as ready-to-wear expanded. A 1970s size 14 typically corresponds to a modern size 10–12. Natural fibers like cotton, wool, and polyester blends were common — some with slight stretch.
1980s Sizing began creeping closer to modern standards but still runs small. Shoulder pads add width without adding size. A 1980s size 14 typically corresponds to a modern size 10–12. Power suits and oversized silhouettes offer more room.
1990s Sizing is closest to modern but still runs 1–2 sizes smaller. A 1990s size 14 typically corresponds to a modern size 12. Stretch fabrics and relaxed fits became more common in this decade.

Tips for Shopping Vintage at HudsonFlowVintage
- Ignore the tag size — always compare your measurements to the item's listed measurements
- Check the listed measurements — every item includes flat measurements in the product description
- Consider the silhouette — a structured 1950s dress has no ease; a 1970s wrap dress is far more forgiving
- Factor in alterations — taking in a seam is easier than letting one out; when in doubt, size up
- Ask us — if you're unsure about fit on a specific item, contact us before purchasing and we'll help you find the right size
How We Measure Our Garments
All items at HudsonFlowVintage are measured flat and laid on a clean surface. Measurements are taken at the following points:
- Bust/Chest — measured straight across the chest from underarm to underarm, then doubled
- Waist — measured straight across the narrowest point, then doubled
- Hips — measured straight across the fullest point, then doubled
- Length — measured from the highest point (shoulder seam or waist) straight down to the hem
- Sleeve — measured from the shoulder seam to the end of the cuff
All measurements have approximately ½" variance. If you need a precise measurement on a specific point, please contact us.
