I got the Brazilian done last year and I loved it! It's the most natural (because it is your fat) but probably the most expensive (I paid $16,000 but also went to a top surgeon in this area of surgery). I had to gain weight to do it because I didn't have enough fat content for the procedure. They lipoed my stomach flat and made a nice arch in my back along with a cute bubble butt.

My advice to you is to research what procedure you are comfortable with cost wise and surgery wise. Research your doctor very carefully because this procedure like any elective surgery can leave you with a lumpy butt. I have seen the pictures...Good luck!
