A medium in the US, a medium in Europe and a medium in Asia are not the same shirt. Regional sizing reflects different average builds and different grading between sizes, which is why the letter alone is unreliable when you buy online.

Use centimetres

Convert once, then ignore the letter. Measure a shirt you own across the chest, shoulder and length, and compare those numbers with the chart on the product page. Our charts are in centimetres and are specific to each style.

Expect variation within a brand

A business shirt is cut closer than a casual shirt; knitwear fits differently again. That is why every style carries its own measurements rather than a single site-wide table.

When in doubt

Send us your height, weight and usual size before ordering. We will point you to the size the fit notes suggest. Sizes run S to 3XL, one piece minimum, 14-day returns on unworn items with tags.
