Start with a nice smile, then say to her "soo..... nice skirt you got on there, maybe you and I can........." wait sorry, thats from watching too many pornos. But seriously, just say hi, ask her what classes she goes to and if she likes them. See what she studies, ANY small talk will help. And heck if it doesn't work out, at least you have practice for the next opportunity that might come up. Dont be shy, the only reason why you would be shy is b/c you're afraid of her dissing you and taking a hit on your "ego" but all signs point to her being interested in you.
