How Much to Size Up
As a general rule: add 4–6 to a vintage US women's size to get the modern equivalent (vintage 10 ≈ modern 14–16). For men's vintage jackets, go up 2 sizes in modern terms. Always verify with a tape measure.
Era-Specific Sizing
1940s–50s pieces run the smallest. 1960s–70s pieces are slightly larger. 1980s vintage runs closer to modern sizing as vanity sizing began to take effect.
