Too short
Size: Medium, Color: White
Fit was okay, but the length was too short. I am 5'5" and if I tuck the shirt into my shorts or pants and raise my arms above my head, the shirt will pull out from my waistline/belt.

Too loose
Size: Large, Color: Brown
The size ran too big/loose. For example, it you tend to wear Large, order a Medium for this instead.
