LOVE these shirts, came back and bought more!
These shirts look SO good. I am a senior manager in a large corporation so have to dress nice every day. I loved the first one of these shirts so much I came back and have now bought 15 of them in different colors. Basically, these are now all I wear. Buy yourself 15 bamboo undershirts with the V neck (you don't want the layered look with dress shirts, you want the V neck so you can't see the undershirt), half in white and half in black to wear under these and you are set. GUYS.....WHEN YOU FIRST BUY THESE YOU MUST IRON THEM. I see the pics of people wearing them here, and you can still see the fold lines from being packaged and that looks terrible. Washing alone won't get rid of the fold lines. Get your iron and set it for POLYESTER which is a lower heat setting. If you set it hot, it will melt the shirt. But set it for polyester and the lines iron out VERY easily and fast. You only have to do this when you first buy them. I've never had to iron any of them again after the first time. They are very wrinkle resistant! I HATE my cotton dress shirts now. These Coofandy shirts STRETCH like crazy! You can bend and reach for things no problem. I'm able to wear all of these with Chinos, dress slacks AND jeans so they are incredibly versitile! My wife and my girlfriend both (joking!) love how soft the shirt feels on me. I have to wear these shirts every day and own enough so I can do laundry once every other week and so far all the shirts have been very durable with no tears, rips, any problems at all. They all still look new.

Must iron first before wearing. Then wrinkle free.
The fit is perfect. The material is quite nice. The only problem would be they are hard to de-wrinkle from original packaging. I’ve washed my shirt several times and it’s still showing the creases. The only way to get rid of them is to launder them or iron them. I think once this occurs, they remain wrinkle free for a while. This is the third of the exact same shirt I got in different colors.

Nice quality shirt
Color: Purple, Size: XX-Large
Nice material and fit is accurate. However shirts are rolled up in a tube, so if you need to wear the shirt the day you receive it be prepared to iron it!

Calidad de las camisas
Color: A White, Size: Medium
I had already bought one shirt, so this time I bought two more. The light blue one is the same quality as the one I bought the first time. But the white one wasn't the same quality. It was also a different shade of white. They should try to maintain consistent quality across the board.
