M.M.
I know 2 women that have had theirs done. They would both say to go in under the boob or through the armpit. 1 went the nipple route, and she did wind up losing her nipple after a painful infection.
Can't speak to size of the bra, but expect to be swollen for AWHILE. As in, months.
I had a tummy tuck and lipo, and it was a full 6 months before all the swelling went down.
Congrats on your surgery!
Oh, and eat pineapple. Seriously...the arnica will help...and pineapple is a natural anti-inflammatory. It will help with swelling. I ate an entire one in the 3 days after my surgery. Definitely helped to naturally rid my body of toxins and keep the swelling down.
