My hips are within the size large measurements and yet their bikinis that don't have the adjustable tie sides still ALWAYS be tight, even when I size up to an XL. They really need to fix that. Ain't no way an actual bottom half XL can fit in this if it's squeezing me and Im a large in everything but these type bathing suits. Breasts kind of hanging out too but that's expected with my chest size. You definitely better size up for the bottoms sis. Otherwise it's very pretty. My stats: 5'10; 36G bra, 30.5in waist, 43in hips. Thick muscular thighs, big calves, perky breast implants, muscular arms.
