Tiraz sizes are based on body measurements, not garment measurements. Measure yourself with a soft tape over a light shirt, then compare with the charts below. A slim fit sits close to the body, a regular fit leaves comfortable room and a relaxed fit is roomier across the shoulders and chest.
Trousers come with an inside leg that suits most, and we hem them for free within 3 days: write the length you want in the order notes, or try the trousers on and ask for hemming at delivery. If the size isn’t right, exchange it within 14 days as long as the piece is unworn and has its tags.
