This is a wing collar shirt, essential for formal occasions such as those requiring a tuxedo or morning coat. It's a shirt frequently used at weddings. Worn only once at a wedding in June 2025, and as far as I can see, there are no stains. It has wrinkles from home laundering, but I believe it can be worn beautifully after ironing. I am 174cm tall with an average build, and it fit perfectly. Color: White Brand: WAWA Size: M (Slim Fit) Please check the size chart.
