Don't listen to anybody but what YOU feel confortable with. A tramp stamp is nothing more than a word invented by stupid people and it means nothing. I think they are attractive as long as they aren't to big, and dainty. It is YOUR body. Do with it as you please. Some people are jealous because they aren't "allowed" to have one, or there nose if to big and it would even show. GO FOR IT!!!! I say it will become part of your personality, and you hve to please nobody but yourself.
Nope I have a nose piercing on my right side and it looks great so great that people at my school started getting their nose pierced after me because they liked the way it looked and if you are going to pierce your nose get the ones on the sides the one in the middle just looks so wrong for girls. Hope this helped! (:
