Won't let me give one star. AVOID THESE SHIRTS
Color: Dark Blue, Size: X-Large
They look okay on first wearing but after washing, you can't get the wrinkles out even with an iron. Sorry I bought these. Won't again. Really, the worst shirts I have ever bought.

Perfect fit
Color: Navy Blue, Size: Large
I bought 2 shirts for summer and have already worn, washed and dried them. They truly are wrinkle resistant. I'm a 6-ft 175 lb male and Large fit me perfectly. The quality seems good, especially for their price.

Small 3x’s
These shirts are great, but the sizes are just a little bit smaller than what they need be that is my only complaint about them
