Size Guide
Vintage sizing varies by era. Always compare our measurements with a shirt you already own.
How to measure
- Pit-to-pit (chest): lay a shirt flat and measure straight across from armpit seam to armpit seam.
- Length: from the highest point of the shoulder (next to the collar) straight down to the hem.
Every original shirt’s exact pit-to-pit measurement is listed in its product details.
