Nice material, holds collar shape well.
Color: Wine Red, Navy Blue, Black, Size: Medium
Good value for the money. You can machine wash and dry on low heat, in my opinion. Laying flat is too much of a pain.

Not made from the most comfortable fabric
Color: White, Light Gray, Black, Size: Large
It is not the most comfortable fabric which makes it not suitable for summer clothing. Also, the fitting of the neck doesn’t look good since material is not wrinkle free
