Each brand's sizes are slightly different. A 55DSL medium may be a different size to a Superdry medium. To overcome this problem we've created two ways to find the perfect fit.
Method 1
Find your best fitted T-shirt and lay it on a flat surface. Measure the width from armpit to armpit and the length from top to bottom like in the picture. Enter the details below (in cm). We will then calculate your recommended size for each shirt you look at.
Method 2
Simply measure the circumfrence of the biggest part of your chest (immediately under your armpits). Then put the dimension (in cm) in the field below. We will then calculate your recommended size for each shirt you look at.
