Fair quality shirt
Size: Large, Color: Port Red
Decent shirt. No shirt if wrinkle-free so take these claims with a grain of salt. The fabric blend will tell you just how much it will wrinkle. If you leave it in the dryer overnight you can guarantee that even if it was made of cast iron, it would likely have a wrinkle or two.
Don't be swayed by a 'label'. The same shirt can have a no-name label sewn on it. Doesn't make the shirt better or worse. It is what it is. Size runs correct. NOT a 'slim fit' shirt, fyi.

Two tone color
Color: Silver GunColor, Color: Silver GunColor
I guess it’s good enough for what you pay but the band and base of the watch color do not match and it’s noticeable.
