I really liked the look and the buttons when I ordered it but I wound up returning only because I have to have a slim or fitted cut for any shirt to look good on me. This shirt did not hug me in the sides and looked like I was wearing someone else’s clothes. Nice shirt and good quality but it didn’t fit me personally. I did consider having it tailored but the cost of doing that was almost as much as the shirt.

Runs way too small

Color: Black, Size: Medium

If you live in the U.S. and wear medium, a large will fill you perfectly. I wear large and the “large” is objectively a medium in the chest arms and neck. Fix your sizes.
