Overall, I liked the outfit and would defiantly order another one, just getting a bigger size shirt.
Size: 3X-Large, Color: Light Blue
I love the outfit, the shirt, which was a 3X was just a little to small. But the pants fit great. The outfit was very comfortable and light weight.

Big guys beware.
Size: 3X-Large, Color: White, Size: 3X-Large, Color: White
All of my shirts, including the green one in the picture, are 3X and they fit great, some are loose. If this linen shirt from Coofandy is a 3X, I’m Mickey Mouse.
