T-Shirt Sizing Guide

Drawing of a t-shirt laid flat shape with lines indicating where to measure sleeve length (straight from where joins shoulder to end), half chest (straight across from just beneath each armpit) and body length (highest point at edge of head hole to bottom of garment)

To find your size we recommend picking a t-shirt you own that you like the fit of, then laying it out flat and measuring across its width in cm, just below the armpits, and measuring it's length in cm. Compare your measurements with the chart below.
