I'm 5ft 11in and 150lbs - a bit slim. I ordered a small and the fit is great but the length was still longer. But for 10€ the quality is great! It's soft and thin, but thick enough to wear as a casual shirt! I am happy with this purchase :)
Pros
Good
Cons
Limited color options. Some buyers may want a wider range of colors than the classic white and navy blue.
