I’ve seen so many different answers to this question as each surgeon seems to have their own opinions. My doctor advised me to wear sports bras with high support for 3 months. I think it’s just down to how you feel. If your scars are healed completely there shouldnt really be an issue with the underwire anymore. Your breasts are still healing for up to 6 months, sometimes even a year but I dont think one or two nights out where you wear a push up bra will affect anything. Well that’s my opinion anyway x
