Hi Roxi,
I would say at least 6 weeks as your boobs need to settle and take shape, so they need the support of a sports bra. One I would recommend which is sooo compfy and doesn’t give you ‘cone’ boobs is the ‘pure lime’ sports bra. I am 6 weeks post op and have practically ‘lived’ in it! It’s def worth the wait, as you have paid a lot of money for the new boobies and you don’t want anything going wrong. I can buy bras now, but my pure lime bra is soooo amazing, I will prob end up continuing to wear it in bed / lounging around!
All the best
