And I mean 40J big. I've started swimming 4x per week and I love it. But I've been trying for so long to find a swimming costume that covers my boobs and is for actual swimming not lying on a beach. I've just had to reject yet another one I ordered and I'm so frustrated I could cry, really cry. It's taken me so long to start to exercise and I feel like giving up. Please help, does anyone have any suggestions?
