I can highly recommend the marks and spencer high impact sports bra with zip front! I was measured round under my existing boobs at 28 so they recommend 2 inches bigger…….32 for me. Then just had to have an idea of cup size. I’ve had 375cc high profile implants so thought a double D would suffice and it fits perfect, nice and comfy, slightly compressed which I find helps. (So initially I was a 32b roughly every 150cc is a cup size bigger)! Hope this helps x
