i havent a clue reecara when looking through some of the othergirls pic say 4 day 3 post op their bras are not on. I think maybe you can take it off to change it but ive got to wear a chest band as well im sure i was told you have to wear the bra 24 7. But also your sugeon will tell you what to do as a lot of girls have said they say diffenrent things x
