Tyra Banks and Hilary Duff weren't the only famous guest stars on Monday's episode of Gossip Girl – designer Tory Burch made a cameo as well.

“I have never acted before, so I was a little nervous about messing up my line," she said, adding that despite all her jitters, "Blake Lively made me laugh and put me at ease though, and the crew was so gracious.”

Though Tory’s scenes weren’t filmed in her actual office, the designer says that the set was a dead ringer: “They did an incredible job recreating my office, down to the বই I have on my Lucite shelves and framed ছবি of my boys!”

While she didn’t get a chance to dress Gossip Girl’s leading ladies, Tory Burch has some ideas on what she would like to see Blake’s Serena অগ্রদূত der Woodsen and Leighton Meester’s Blair Waldorf wear from her real fall collection.

“Serena’s style is sophisticated yet rebellious,” says Tory. “I think she’d live in leather leggings, with an embellished শীর্ষ and oversized vest. It’s a cool, sexy look Serena could wear uptown, downtown, and everywhere in between.”

As for Blair Waldorf? “[She] has a quirky ladylike style and looks great in contrasting colors, prints and textures."

"The booties and leather driving gloves add just the right amount of edge. I would add a custom-made headband that would be cool enough - even for college.”
