"The Look"

I've often wondered why girls have this sick desire to all look alike.  But, after coming to college, I've realized this: if a girl wants to get into a sorority, she has to have the look.  The straight, typically blonde hair, the tan skin, the excessive amounts make-up, and the skimpy clothes.  These are all physical attributes that nearly all sorority girls have.  I have yet to meet a sorority girl who looks, for example, like me: curly reddish hair, freckles, pale complexion, short and petite.  I do not fit into the stereotypical sorority girl form.  But why do sororities have this stereotypical image that their members must have?  Is it that they need to attract the most attractive males?  Do they feel the need to think that their sorority is the "prettiest"?  Do they seek to set high expectations for all other girls in the way they think they should look?  And is it fair to be exclusive based so heavily on appearance?

Walking around campus to my classes, I am struck by the girls who I pass.  Why do they all look so similar?  Each face is unique, but covered in too much make-up to really see the differences.  In many, many cases, all I see is blonde hair, heavy make-up, and tan skin.  Is this an attempt to reach the "ideal beauty" that is advertised in magazines and commercials?  My thought is this: why are sorority girls so predisposed to trying to look as "beautiful" as possible, instead of being naturally beautiful with what they were born with?  There are plenty of things about my appearance that I dislike, but because I believe in loving myself for who I am, I deal with what I have.  I make it work.  I feel like sororities put so much stock in appearances that their members can not truly embrace who they are.  How is this okay?
