How we measure
- Chest — straight across the front, armpit to armpit, jacket zipped and laid flat. Double it for the full circumference.
- Body length — down the center back, from the collar seam to the bottom hem.
- Sleeve length — from the center back of the collar, over the shoulder, to the end of the cuff.
