Such a nice suit!
Size: 14, Color: Beige
I was pleased upon getting this suit for my son. I really like the color, which is kind of like an oatmeal color. Nice and light color. The material is light and thinner, but very comfortable. It fit my son really well. It’s not lined or the best quality suit, but because it is a linen suit, it works out and look really good. I would recommend this one, especially for more of the summer/spring time.
