Let's talk cool celebrity trends.

Take a cue from O.C. cutie Rachel Bilson (or the stylist from her last Nylon cover shoot) by toughening up a sweet party dress like this ivory cream dream with a rock star grommet belt. Everyone loves the unexpected.

Another celebrity trend I'd like to try? Dating other celebrities. As far as I know, Rachel's still hooked up with her Jumpers co-star Hayden Christensen aka Anakin Skywalker.

Forgive me for my UsWeekly moment. Back to fashion...

Get the dress from Delias on sale for only $14.99, and save even more cash by snagging a belt from your garage band boyfriend's closet.

It's my party and I'll wear a belt if I want to.
