Frequently Asked Questions
How do I find my suit size?
Measure your chest at the widest point in inches. That measurement is your US/UK suit size.
What is EU 50 in US suit size?
EU 50 ≈ US/UK 40.
What do S, R, L mean?
Short, Regular, Long — they refer to jacket length, not chest size.
Should I get my suit tailored?
Yes. Off-the-rack suits rarely fit perfectly. Buy for chest/shoulders and tailor the rest.
How do EU suit sizes work?
EU sizes are roughly US size + 10. So US 38 ≈ EU 48, US 42 ≈ EU 52.
