I bought this shirt few weeks ago with no glue if the size will fit or not. I already have some really small fitted shirts from Rogue which are more "body-hugging" and due to the reviews I ordered XL which was really good (normally I am a big M or small L) and the XL within other shirts was absolutely necessary (they fit completely body-hugging which is nice with jeans but not for doing sport). As I am located in Germany I do not wanted to send shirts back and forth therefore also if the fitting table said I should order a L within this shirt I again decided to order the CL to be on the "safe side" as no reviews where existing yet. And I can prove you this shirt fits the "normal size". So it is bit big for me and more relaxing but due to the nice light material it does not look too masculine. It's a nice combination with leggings and also absolutely good for doing sports. So if you are between a M and L in normal clothes a L is absolutely fine without beeing too tight. If you like to have it oversized a XL also do not look bad. I think I will order it once again in L because I really like it a lot and then I do have one oversized for doing sport and one which looks a little bit more feminin :-) (I am 1,70 m and 77kg athletic)
