I had partial unders, and has to wear the granny bra, I was 34 b to begin with and bought a 34 d but had to change to a 34dd after 2 days as it was crushing my boob’s. Felt so much better when I’d changed. All of the bras rubbed on my scars until the end of week 2 but that’s was when all my bloating went away, so I think that’s what the problem was. Now I’m 4 week po and have kept my d bra just in case it was the swelling that made me a dd, I tried to wear it yesterday and it still crushes my boob’s so sticking with the dd, which I’m happy about lol. I found the m&s granny bra the comfiest
