Fit & Sizing

SIZE GUIDE

Vintage sizing does not match modern standards. A vintage Large often fits like a modern Medium. Always go by the measurements below, not the tag on the garment.

How to Measure

ChestLay the garment flat. Measure straight across the chest from armpit to armpit. Double that number for the full chest measurement — our guide uses half-chest (pit to pit).
LengthMeasure from the top of the shoulder seam (at the collar) straight down to the hem.

Good to Know

All our measurements are taken with the garment laid flat.
Vintage cotton has often been washed many times — slight shrinkage is normal and already reflected in our measurements.
If a product listing has specific measurements, those always take priority over this guide.
