I'm really struggling to find a supportive wireless bra that doesn't give a mono-boob! Any suggestions? I think part of my issue is I am a 30FF, so any sized as XS, S, M etc generally fit around the ribs but too small in the cup and if I size up to accommodate the cup, it's too big on the ribs. Have tried Boody, and while it's comfy, it's just a complete failure in keeping things separate and mono-boob is not a good look!
