Great shirt, unfortunately wrong size
Color: Royal Azure, Size: Medium
I bought the royal blue azure variety, and I really love the color. I also really liked the material, it feels light and silky. It works great as both a casual and semi-formal button up.
Unfortunately, the shirt was too big, hence the 4 star rating. I am usually a size M, but this shirt was very long, reaching almost the halfway point of my thighs. I think you would be better off ordering a size below. For this color, they didn't have any smaller size, though, which is sad because I really liked the shirt otherwise.

Great value
Color: Grayish Blue, Size: Large
Nice shirt, runs a little small. The fabric is nice and the color was great. I am very pleased with this purchase. Probably will buy several more in different colors.

Classy button shirt for dress up or casual occassions
Color: White, Size: XX-Large
I love the COOFANDY button down shirts!! They are soft, fit well, perfect length, maintain their color, and can be worn for casual or a fancy night out on the town. I’ve bought (4) of these so far.

Comfort
Color: Grayish Blue, Size: X-Large
The only thing I would change about these shirts and I've bought 9 now is the extra button they give you comes on the tag and not on the shirt like I'm used to so I lost the buttons. And I have a shirt that's missing a button now. But overall definitely a good shirt fits how you would expect. And is not cut overly short like a lot of dress shirts are nowadays

Great button up
Size: X-Large, Color: Blue White 168
This is a very nice button up foe my husband. The fit was true to size and makes a great church shirt that looks nice with slacks or jeans. Seems well made too.
