i'm 34 years old, 5'6", 150-ish lbs and i'm pretty cute, i have a fairly healthy self-image but would still feel a little uncomfortable, on a bad day, standing next to a gorgeous girl like this in a bikini on the beach... HOW SHE WAS BEFORE!!! with charachter in her eyes and smile she was memorable, to me atleast, i thought she was freaking adorable... to look at anyways, and now i look at her and there is nothing about her that i'd remember. NOTHING! i'd stand next to the "new" heidi in a bikini while i was bloated after a huge break-up and still feel like i looked better, cuter, more attractive because i've got unique-ness.  she took away her cute! girls don't understand that our little imperfections are what make us attractive.  if it's going to make a huge difference in how confident you are about yourself then ya, go for it, after alot of thought. but perfect is ridiculous... in whose eyes? guaranteed you're perfect in somebody's eyes. feel good about you, if you don't, figure out why and work on it... but inside, not under a knife or knives. confidence is sexier than anything you can put on or take off or augment or whatever.
