Reseller tips
- For men's clothing, US and UK sizes are usually the same number.
- EU / IT sizes are typically 10 higher than the US / UK equivalent (US 40 ≈ EU 50).
- Slim-fit and regular-fit labels vary wildly between brands — note the actual chest measurement where possible.
- Suit jackets use chest size in inches (US / UK) or centimetres (EU).
