Step 01
Your body measurements
Before checking your size, take a few simple measurements. Use a flexible measuring tape and keep the tape comfortably against your body without pulling it tight.
Compare with a garment you already own
Have a garment that fits you well? Lay it flat and compare its measurements with our garment measurements below.

T-shirt
Chest
Measure straight across from armpit to armpit.

Trousers
Waist
Measure across the waistband.
This is a secondary method. Measuring your body is the most accurate route.
The most common sizing mistake
Our size charts show the finished garment, not your body. Do not match your 100 cm chest to a 100 cm number in the chart.
Your body measurements
Measurements taken directly from your body, with a tape.
TA garment measurements
Measurements taken from the finished garment. This is what our charts show.
These numbers refer to the garment, not your body.

Between two sizes?
Our True Muscle Fit is cut to sit close to the body. Going up a size keeps that shape and gives you more room to move.
