What do I do? My best friend is prettier than me....?

My best friend is great. I do love her and I can tell her anything, but when we go out to our favorite dance place, movies, mall, or anywhere she gets hit on by all guys. She even had an old man who had his kids with him ask her out and I was right beside her. I am always beside her when she gets hit on. She is 5'4 and a little round, but very cute, brown hair, blue eyes and she looks like Snookie (From Jersey Shore), but not trashy. Anything she wears looks great. Then there is me 5'6, brown hair, blue eyes, and fell ugly when I am around her. Is it because I don't wear as much makeup or that she is tan or what?? What can I do to get guys to look at me too?
