I’m a 36H.
Im 51 and I don’t think I’ve ever had a comfortable bra. I’ve been through all the fittings possible including boob or bust and they have all settled on 36H so I’m confident that’s the right size
This will sound weird, but I have large ribs. I have some harmless cartilage growth on them which makes them protrude more than usual and so under wires really tend to sit on them and rub. I’m really starting to get sore underboobs from rubbing and sweating.
I’m looking for a non wired bra with support and hopefully in a natural fibre, the underwire just makes everything uncomfortable for me.
