Cool, modern look
Color: Army Green, Size: Large
I bought this for my husband and looks great! The material is a little clingy, so I would get a one size up for a better fit. He has received numerous compliments. It fit him well and I washed it but played it flat to dry with no shrinkage problems. I highly recommend it. We ordered another one in a different color.

Too big
Color: Pink, Size: Medium
Seems like good quality, the sizes run big, I normally wear medium in most clothes, but the small is still too big for me

low-maintenance shirt that fits perfectly
Color: Black, Size: 3X-Large
This COOFANDY Casual Button Down is a fantastic addition to a summer wardrobe, offering both great fit and high quality. The material is impressively wrinkle-free, which keeps it looking sharp and crisp even after a full day of wear. It is specifically designed to be worn untucked, and the length is just right—offering a modern, relaxed silhouette that doesn't look sloppy. The fabric feels durable yet breathable, making it comfortable for both casual outings and slightly dressier occasions. If you’re looking for a low-maintenance shirt that fits perfectly right out of the wash, this is an excellent choice.

My husband loves these shirts
Color: Dark Blue, Size: Large
My husband just loves these shirts. He has one in every color, I think. Great quality, good price, breathable, true to color, and super comfy. Nice enough to wear to a nice dinner but can be dressed down w a pair of shorts and flip flops. By far the best find I have found!
