Good but a little small
Color: Dark Grey, Size: Large
Seems worth its price, nothing fancy. It's tight in the shoulders but a size up would become too boxy in the waist for me. Didnt shrink too much so the size it arrives as should tell you.

Nice looking shirts.
Color: White, Size: Small
Fits well. It's a nice-looking shirt that can be worn on its own or layered over another shirt. It is somewhat thin, so it's more for milder weather.
