This shirt might have been correctly sized for the measurements given, I didn't check, but the medium was larger than I expected from this size. It was also missing the bottom button. I know there are replacement buttons inside but I'm still sending back because the size; ordered a small instead. I went with this one because someone said contemporary fitting which I took to mean more slim fit and less boxy. It seemed to be decent but I'll know better when I get the small in. Other than all that the material and embroidery seemed pretty great for $24! I'll change to five stars if the small fits well and it has all the buttons!UPDATE:The small came in, fits very well except a little tight if I extend my arms all the way forward. A small sacrifice to get a more form fitting shirt; really don't want to wear anything boxy. Just doesn't look good. It had all the buttons! Material is pretty good and stains come out easily. I never need to iron it and it does well in a standard wash cycle and low heat dry cycle. The collar will bubble up a little bit but can be mostly ironed out. I've seen the happen on a lot of guayaberas and it doesn't bother me. Can't beat this for $24.
