I am 5’4” and 126-129 lbs, I have a 26-27” waist and a 34DD (maybe D now) chest. I purchased a small. it was only *slightly* too small for my tatas, but DANG did it lift and shape me amazingly well! I’m @mayyedarling on instagram if you want to see it on me: a pale, freckled, blonde, white girl (even despite risking a possible washout, this set actually POPS on my skin!). I wish they had more colors!! I’ve worn it about 3 times now, and even washed it (delicate cycle, no dry) and it still looks great!
