Buy one size smaller from what you normally wear. I don't know how people say this fits as expected lol. I wear a large in ANY other shirt which definatley are not loose. I bought a large in these even though its relaxed fit and it was like a night gown. They are awesome though and great material. Refunded with no issues and just ordered mediums and they were still a little lose. A medium in any other shirt is skin tight on me normally.
