I used this about twice a month for about two years. I used it for parent-child swimming with my child. The top is size 15LL, and the bottom is size 11L. I am 160cm tall and have a standard build overall, with a slender upper body and larger lower body. The bottoms fit perfectly, and the top was a little loose. Because it stretches, I think it would fit someone who is a little larger. The fabric is sturdy, and there are no stains or frays. (I just realized now that the top was size 15LL even though I ordered size 11L...)
