i wear a size small in women's, and i'm petit so i ordered an XS and it fits amazing!!!! so comfy!
Bought the T-shirt as a Christmas present for my boyfriend, as I know he really loves Good Mythical Morning and watches it all on YouTube (I admit, I know nothing about it). It arrived in the UK quickly, in time for Christmas Day and he absolutely loves it! He loves the design, the fit and he wears it all the time.
