Stick to your size, I went down a size after reading reviews that said it has stretch, Yes it does but not like that. These ppl are squeezing into clothes. It's cute , sexy asf, a lil itching, thick and doesn't look cheap. Small was a lil snug on me. I reorder my size M even tho I can't get my money back due to final sale. I'm 5'5, 38D, 145lbs, 33 waistline, non curvy, but I got a lil shape , lol & this was giving what it suppose to give
