Pros: Less scarring than traditional lift (no vertical scar)
Cons: Longer recovery (but worth taking the time to get a better product)
My motivation: Backaches (I'm a dentist) were becoming a problem, even "minimizer" bras put a lot of strain on my shoulders. I had DD's from the time I was a teenager, so with time they had sagged. I felt self conscious, about "bouncing" as I walked. In order to work out, I had to wear several sports bras.
Outcome: Great results! I can wear those cute dresses with open backs, even go bra less (though usually I wear one day and night). It is amazing and life changing, I would recommend it to anyone over a C cup who is considering implants, because although I went from a DD to a D, they appear bigger, I look slimmer (even though I'm the same weight) my posture is much better, I don't come home from work with backaches (haven't been to the Chiropractor once since I had the procedure). I almost cried the first time I put a bra on sitting upright (previously had to bend down to get them in the right place). I feel much more confident about my body now.
I wish I knew beforehand to take more than 1 week off to recover. I also would have gone shopping more beforehand to make sure I was more prepared with well-fitting/supportive bras because I didn't have the right ones so I had to go to the store when I wasn't feeling great and buy bras without trying them on while I was still healing, which can get expensive (the cost below doesn't reflect this additional cost for new bras).
