Hmmm, before you get a nose job, you realy should try to get more confidence. If you get it done and it doesnt look quite the way you expected, you will be even more paranoid. Also, i hear that they are very sensitive once done. So if you get a slap for seeing someone elses bloke, it could prove very costly...
I had a consultation at The Pountney Clinic in London to get my nose done a few years back (probably 3) and it was going to cost me �2,400. I wanted mine shortedn and slimmed. I assume it depends on exactky what you want doing
