After reading the one review, and normally ordering XL, I decided to order a L. It just fits, please ignore other people's reviews and use your own judgement (Levis do offer 90 days returns) also had the same experience with the "Felix the cat" hoody, just right, not "if you normally order L, order a M.......

Was happy to see the shirt when I first got it. The material was nice and thick, much better than the other Levis shirts I purchased. I know my Levis shirt sizing is usually large but this shirt was unusually big. It looked like an XL or maybe even bigger. The sleeves were huge and it was very baggy on me. Yet the shirt both on the label and the inside that it was large. I'm not sure if this is an issue with all the shirts or I got a defective model. Unfortunately had to return it.
