Calvin Klein swimwear always fits to perfection. Would not wear any other brand.

This suit is just perfect, except for the fact that the leg openings are too big, at least for me.  I prefer to keep my buttocks covered.  The only way the leg openings fit is by sliding up about a quarter above the crease between buttocks and legs.  I could pull the back down, but then there was a gap between me and the suit leg opening.
