I think you just need to wear a sports bra or post surgery bra, it does not have to be the macom. I am 10 days post op and I have changed into a front-zip sports bra form M&S, its so comfortable and more flattering when i put clothes on. I went a band size up to make it more comfortable. I was told to wear this 24/7 for 6 weeks, until my 6 week check up, then after that we can go into normal bras as long as they dont have underwire x
