Hi Hun. You’ll usually get that info at your pre op.
Usually you wear a post op bra for 6 weeks 24/7 like a MYA bra or a MACOM. I have 3 Macom and find them super comfy. They come in small / medium & large. If it fits before it will fit after.
I had my dressing on for one week then redressed and they were finally removed for good at the end of week 2. The nurse at your clinic will dress / remove them for you.
It depends on your surgeon as to whether they’ll use strapping or not – if you do have strapping it’s usually on for a week give or take.
Hope this is enough info for you xx
