I don’t think you have to after 8 weeks but in my opinion it’s best, just because you have implants doesn’t time an they won’t sag just like natural boobs if anything they will sag quicker as the weight of the implant, if I was you wear a sports bra to bed forever lol I haven’t bad. A night off without mine since iv had them done and that’s 10 months, honestly it’s be best thing it will stop them from going shit basically and I always wear a sports bra around the house if I’m just lounging about xx
