Send your measurements

Follow the photo guide for each point, then enter the number. Our tailor will cut from what you send — precise, with no hidden fees.

All measurements in centimetres. Best taken by someone else, over a light shirt.

Flexible tape Use a soft tailor’s tape, not a metal ruler.
Light clothing Measure over undergarments or a thin shirt — not a coat.
Stand naturally Relax your arms. Do not hold your breath or suck in.
Ask for help Shoulder, back and sleeve are more accurate with a second person.
