I agree, don't worry about what the other girls wear or think. As long as whatever you wear you are comfortable with and have confidence in.
If your friend is going to try and say something to you about wearing a thong...well tell her they are more comfortable for you. If she has a problem with that...well its HER problem not yours. She is probably just jealous cause she doesnt have one..
I personally am not a big fan of thongs...I save them for the special occasions...for seamless look or to feel more sexy (can I say that to a 15 y/o?).
Do what you do, Be who you be!
