If you haven't already checked out Ralph Lauren's Pink Pony charity auction now's the time for two reasons: A) Because there are priceless prizes to be had, like the chance to own a Ralph Lauren gown worn by Penelope Cruz (left), a coveted front-row seat at a Ralph Lauren fashion show (top right), a personal shopping trip with Gossip Girl stylist Eric Daman, and a one-on-one lunch with InStyle's own Fashion Director Hal Rubenstein (bottom right) and B) Because it ends tomorrow! And you can feel good about making your bids since 100% of the money you spend benefits Ralph Lauren's Pink Pony Fund to fight breast cancer. See all the prizes up for auction and place your bid now!
