I wouldn’t recommend this to anyone. The quality felt cheap.

I'm 5'4", 123 lbs, and somewhere between a B and a C cup (they've grown recently). I own a Small lingerie that fits me perfectly. I thought this S/M would be slightly loose but still a good fit... it is not. It's so small on me that the boob part pulls my boobs down to my belly and I can barely breathe. I heard small ripping noises while trying to get it on me. It was so complicated to put on too, it took me over 5 minutes to figure out how to put it on. Frankly, my entire $100 order was like this. I ordered a Large on this website and it was tighter on me than the Small lingerie I already own. Extremely disappointing.
