Color and size were great, but it came with some wrinkles and creases.
Size: 5X-Large Big Tall, Color: Olive Green
The color (olive green) and size were perfect. The shirt is comfortable, and i did not see any bad stiching. The fabric is a synthetic and it came with a bunch of wrinkles and creases. I'm hoping with several wears and washings that the initial wrinkles will smooth out -- if that happens, then I'll update this review.

Sizes differ
Size: 3X-Large Big Tall, Color: Pink
Sizes differ from each style shirt. A 3X in one style does not fit the same as a 3X from a different style even though it is the same company. The ones that I could find that fit were a nice shirt and comfortable. I would not rule out COOFANDY after trying one style shirt. To be honest I can’t remember if I kept this shirt or returned it but the return policy allows you to try different shirts so well worth the money to give it a shot. I needed a pink shirt to match my wife’s dress so I tried a couple different ones and ended up with a couple nice shirts at a reasonable price.

Buy lots of them!
Size: X-Large Big Tall, Color: Blue
My husband is big and tall, he wears XXL, these shirts are long enough for his waist, wide enough for his shoulders. They are very soft. They wear well. If you leave them in the dryer too long, it is easy to get the wrinkles out. Mist it with water and throw them back in and Wal-La no wrinkles. Love these shirts. Very well made.
