well all i can think to say is, everyone has somethiing they dont lke about them selves, but the thing u should get is, no matter what other girl is in the room weather she be skinner or taller or have huge boobs or whatever it is, when your on stage people are watching YOU not them.
and the things you dont like about you, are things you notice but other probabaly dont, you just focus on them.
honestly, in just as bad but u know what, not once has anyone said to me "you were good but i couldnt stop looking at htose faided strech marks on your hips" or "yeah you were ok but not as skinny as some", generally the reaction is "wooooo! "

so hold your head up hig, there isno one perfect woman and there is no one type men like only, so go out there wiggle all you want and have fun, cause the fun is the most important thing.
