Tiffany & Co. may seem like a daunting institution on Manhattan's famous Fifth Avenue, but last night the jewelry icon was all fun and games. To toast the opening of the flagship's home and accessories floor, as well as the new Blue Box Cafe, stylish insiders and A-listers sipped champagne with CEO Alessando Bogliolo and chief artistic officer Reed Krakoff at an after-dark bash full of Tiffany blue.

Olivia Wilde, Riley Keough, Aimee Song, and Jessica Joffe all made appearances, joining guests in checking out the stunning eatery on the fourth floor as well as a display of Tiffany's "everyday objects" collection, including a $9000 ball of yarn and those buzzed-about "paper cups" (made of bone china, natch). While Olympic table tennis players made use of Tiffany paddles, the Guinness World Record Holder for Card Stacking, Bryan Berg, built a breathtaking house of cards as attendees looked on in wonder. Partygoers were also able to sit for a sketch by illustrator Richard Haines, completed with a sterling silver Sharpie, of course. Olivia and Riley even tried their hands at the three ball cup game, but some slight of hand had them beat.
