If You Have: Remnants of the '90s (jean jackets, backpacks, overalls, floral dresses, chunky cardigans). Or, for that matter, anything Charlotte Ronson or Madewell has done as of late. And a hat: preferrably a floppy one that you can tape a flower to.
Bonus Points: For unabashedly saying "Whoa!" all night, even when it gets really, really annoying.
