The fit is incredible. Run a little smaller than normal, im 5'4, 128 lbs, my hips are 40 inches and my waist is 26 inches and the mediums fit like a glove!!!!! PERFECT!!! they are low cut but not extreme, and the back is a modest thong.. if thats even a thing. SLIGHTLY less coverage than the photo but still have the extra fabric up top. perfect, perfect, perfect.... getting the pink, purple, and orange as well. this will b my go to bottom for all my bikinis this summer. not too tight, still room to move , nice amount of stretch but not full on spandex stretch.  glad i bought these!!!!!!!!!
