These are great shirts
Color: White, Size: XX-Large
These are very good shirts. Good quality, good material. The size descriptions are accurate, so they're a great fit. The stitching and buttons reflect good quality, the buttons are good and secure, too. I highly recommend these shirts.

Fit fail
Color: Red, Size: Large
I don't like to give bad reviews but I will at least give an honest review. I purchased this shirt in red and was pleased with the color once I received it. My problem was, that when I tried the shirt on, the fit was good but the collar noticably too big for the shirt size. Looked like something from the '70's. I returned the shirt.

Solid shirt for the price — looks sharp and fits great
Color: Light Grey, Size: 3X-Large
I picked up this COOFANDY long sleeve shirt for work and casual wear, and overall I’m really happy with it. The fit is true to size and it’s not too tight or too loose — just a clean, regular fit that looks good on its own or tucked in. The material feels comfortable and not overly stiff, which is nice since I wear it all day. It has a crisp look but still feels soft enough to wear without feeling like you’re in a dress shirt all day.
The stitching and buttons seem strong, and the shirt holds up well after washing without shrinking or losing shape. I also like that it’s easy to iron (or even just hang up right after drying) and it still looks presentable. The collar stays in place and the overall style is simple and classic, so it works for interviews, work, or even going out.
For the price, this shirt is a great value. It looks more expensive than it is, and I’d definitely buy another color. If you’re looking for a reliable everyday dress shirt that fits well and looks clean, this is a solid option.

Good valued Polo Shirt

Absolutely fantastic value. Quality shirt....love the texture however, when ordering, size up. I normally take a large however, the XL was a perfect fit.

Nice shirts! Fit perfectly!
Color: Dark Green, Size: Large
REALLY nice shirts! Bought dark green and black for my 23 year old son before he left for his six month cruise job to East Asia and they look to not wrinkle at all, plus they fit perfectly and look great! He's 5' 10" and about 170 lbs and wears a large. It fits a little loose, but he likes it that way. I would highly recommend these shirts!
