I am a large woman with a large bust. I ordered the size I thought I needed. It fits really well now. However, I'm losing weight, so I should have ordered a size smaller. That is my fault. I have tried many, many, many sports bras without any luck. They were all too small to hold me in and still while I rode my horse. The Shefit was amazing. I had no bounce with my FF girls. So, since I ordered one that would fit now, I'm going to have to order a smaller size in a few months. That's a good thing. I love the adjustability the Shefit offers! AMAZING bra!!!
