Last night, the stars came out to celebrate the new Sundance Channel series, "The Day Before," which follows designers Sonia Rykiel, Proenza Schouler, Fendi by Karl Lagerfeld and Jean Paul Gaultier, in the frantic final 36 hours leading up to their runway shows.
Not only were Jack McCollough and Lazaro Hernandez (of Proenza Schouler) in attendance, but their pal (and Gossip Girl extraordinaire) Leighton Meester got all decked out in Proenza for the event, and rock heiress Alexandra Richards turned up to DJ the event. Oh, and did we mention Rachel Zoe was there, too? Needless to say, this is a fashion week must-see.
The four part series will be airing throughout fashion week, so you'll have multiple chances to indulge in your behind-the-scenes fantasies -- personally, we're probably most looking forward to seeing Karl in action ...
