I ordered a medium and it appears to be on the large side of what I would expect in a medium, although not too much so. And judging by the material, it will shrink a lot. Unfortunately, it's not my idea of a premium t-shirt: 2/3 poly, 1/3 cotton, and so thin it is basically sheer. All that said, it'll do. I'm happy to have it and expect I'll wear it from time to time.
