I would definitely recommend the Macom Bras. You just need to buy a size up from your normal bra size. I normally where a 34, so I got a size L (36) in a Macom bra.
It’s not that expensive, I bought mine for like £37 and that includes shipping + discount code.
I also bought 2 M&S post op bra’s, I was advised to buy two cup sizes up from what I normally am. I got a C and a D. Luckily I got the Macom bra! Because I can’t zip up M&S bra. The D cup size fits my boobs but doesn’t on my back so I might exchange one for a 38D.
When my Macom bra arrived, I thought the material looked cheap, it is much thinner than the picture makes it out to be. But I’m so glad I bought it, it’s great because it moulds to the whatever size you are. The adjustable straps come in handy.
When the nurses put on my bra after surgery, it was pretty easy to slip on. But I know if I used my M&S bra they wouldn’t be able to.
I hope that helps 🙂
