Why do girls go to extremes to be attractive?

Because of GUYS, pure and simple. And men are extremely hipocritical when it comes to this subject. Here's the deal; girls see men fantasizing over celebrities and porn stars who are "perfect" with there dark tans, fake boobs, perfect hair, and makeup done perfectly as well. So we see what guys supposedly want and are atracted to, so then we in turn try to mimic these "perfect" girls by getting all made up and "perfect". Then after we do that, the same guys who were fantasizing over unatainable celebrities turn around and call us "fake" and tell us were "wearing too much makeup". When all were doing is mimicking the same girls you are fantasizing over. Blame the media and yourselves.
