Perfect Color
This shirt is so soft and the color is as depicted. Great mock turtle. Size is as expected. Ordered a large- 5’9 165# It fits well maybe a bit long but I wanted it loose.

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.
