I'm a comfortable size 36 and couldn't even reach the first hole in a size 36 belt. I have doubts about whether a size 38 will fit me and simply refuse to buy a size 40 belt. although it looked nice.
Pros
It's hard to find a product of this quality. Looks great. Well done, maybe the best white belt I've ever had.
Cons
Belt buckle not securely fastened and tends to loosen
