Get a bra after you see your surgeon. He’ll advise you what size to get. If not ask him at the time when you discuss the size of implant your going for.
You can get the bra anytime. Just make sure you have it ready for after the op.
My surgeon told me at the time. Could even text your pc to say your wanting to wear a sports bra after the op. What size should you get? She’ll be able to confirm.
When u see your nurse she will advise u what to buy, BUT she told me to get 34D when in fact I got 34E and could go 1 bigger so personally I would get bigger x
