I am a small XL so after reading description and other reviews I bought down to a L originally. The L was too small out of the package so I returned it for an XL, which fit nicely. Just comfortably big. First wash, in cold water, no dryer, it shrunk quite a bit, to the point it's now on the tighter side. I love the feel and look of the shirt so I'm disappointed as I know if it feels tight I'm likely not going to wear it. Bummer.See full review
