Okay honestly you can just leave this one with FN not worth it. Cheap material. Rides ya the whole time! Ordered a M. I’m 5’6 160 pounds. I’m your averageee. Average 34/36C. Size 8-9 usually a M bloated days a L. dress size small/med…swimsuit usually M. Everything usually a MED for the most part. If you have full cups there’s NO space to put your boobs. Made for small boobs. Just uncomfortably not worth it.
