Sorority house halloween party

As you look around, you see dozens and dozens of sexy college girls everywhere! You quickly figure out from the costumes and decorations that you are in a sorority house for a halloween party.

Hot girls dressed as all kinds of sexy things surround you. You are wearing just a Charlie Brown-esqe white sheet like a ghost (you only have two eye holes though).

Over there is a sexy black girl dressed in a Beyonce wig....
Next to her is a hot blonde girl wearing a slinky cat costume...
To your left is an amazing hottie wearing a very short witches' costume...

So many choices...You feel like a kid in a candy store!

Who should you approach? Beyonce? The cat? The witch? Look around some more?
