In every bit of kit I've bought, and ive bought a fair bit, from Gasp I've needed medium. This tee is a bit too small and should have had large. As much as I'd like to think I've gained muscle the fact is all the rest of my kit from Gasp still fits so it's cut small! Bought in flash sale but in the time it took to arrive sale had ended and couldn't pay double the price so I'll wear it or give it away whichever best suits.
