Frequently Asked Questions
Are US and UK men's sizes the same?
For shirts, jeans, and most casual wear — yes, identical. For shoes, UK is 0.5 smaller than US.
What's the difference between a 40R and 40L suit?
Both have a 40-inch chest. R = Regular (5'8"–6'0" height); L = Long (6'0"+); S = Short (under 5'8"). Same chest, different jacket length.
How do I size a slim-fit shirt vs regular?
Slim fit cuts the body 1–2 inches narrower at the same chest spec. If you're between sizes, size up the chest and have the body taken in.
What if I have an athletic build (broad chest, narrow waist)?
Look for athletic-fit lines. They're cut with a 7–8 inch drop (chest minus waist) vs the standard 5–6 inch drop.
