Teen girls...who here has problems with panty lines?

So I just got a brand new pair of these blue hollister skinny sweatpants (the tight fitting kind). so I wore them yesterday but when I got home i happened to look in my full figure mirror and lo and behold, PANTY LINES. i was so embarred. Not only could you see the panty outline, but also the lines where the panties wrapped around my legs and stuff ughhh so embarring. My parents won't let me wear thongs, so that is completley out of the question, and I can't go without panties. My first quesiton is: how many of you have problems with panty lines and also, how do you get rid of themm??
