With Christopher Kane, Jonathan Saunders, Richard Nicoll, Roksanda Ilincic, Louise Gray, and Mary Katrantzou as a few of her famous alumni, we just had to ask Wilson if she had an LFW favorite this season: “Well, I don’t like to pick and choose, but it has to be said that Louise Gray’s show was outstanding—she really went to another level of her career. If I was younger, I’d be wearing all that stuff. Well, maybe minus the mohawk.”

Gatta’s pieces will be in stores this spring at New York’s Kirna Zabête and Julie Skinner’s vintage haven P.S. Postscript Couture in the Meatpacking District, but her six-dress collection (sketches, below) to celebrate the 50th anniversary of Lancetti is already available (and selling well, she reports) on Yoox.com. For the birthday tribute, Gatta scoured the back rooms of Italy’s fabric shops for original Lancetti prints and reinterpreted them in her own contemporary style. In the pipeline for Gatta is next spring’s collaboration with primo Italian silk printer Mantero in Como, whose extensive print catalog for the world’s top designers has her in a state of bliss. “The real difference this time is that we will be reprinting, which means it’s no longer limited-edition and I can mix patterns on unexpected fabrics like lace,” Gatta tells Style.com.

Lars von Trier has enlisted musician-actress Charlotte Gainsbourg to do a third film (Nymphomaniac) with him. The movie “follows a woman’s erotic journey from birth to the age of 50 as told by the main character, the self-diagnosed nymphomaniac, Joe.” [Hint]

The U.K.’s first lady, Samantha Cameron, who serves as an ambassador for the British Fashion Council, has been popping up at various runway shows throughout London fashion week. She sat front-row at Burberry and Christopher Kane over the weekend and attended the first-ever McQ runway show. [Huff Po]

The crowd—including Rihanna, Kate Moss and Jamie Hince, Mario Testino, Juergen Teller, the Le Bons, the Driver sisters, Stella Tennant, Bianca Jagger, and belle of the ball, Shailene Woodley—was well seeded with models in Stella dresses. Not, they insisted, the clothes we had come to see. “We’re just guests,” said Kinga Rajzak, dazzling in a black sheath with a white contoured effect. She was one of the new guard of girls on hand. Shalom Harlow, Amber Valletta, Yasmin Le Bon, and Anouck Lepère were also wearing Stella gowns, ranging from variants on the contouring to marble-printed bubble dresses to confections spun from vibrant orange or electric blue lace. Lucie de la Falaise brought daughter Ella on her first big fashion night out. Appropriate, then, that they’d be staying over at godmother Moss’ London pad.

After guests chomped through a veg feast of five small but perfectly formed courses, Dutch illusionist Hans Klok, World’s Fastest Magician, took to the stage. He laid a hypnotized Alexa Chung across three huge scimitars and left her essentially floating in mid-air, balanced on the sword on which her head rested. Trance state or not, she claimed she could still feel the point of the blade an hour later. Childlike glee is always my default position with magic tricks, but surely this was not the “something big.” Suddenly, there was an almighty shriek from a nearby table, where it seemed like a scrap had broken out between a guest and a waiter. Then Led Zeppelin’s “Immigrant Song” came walloping over the sound system, and all hell broke loose. Models, waiters, and Shailene Woodley flew hither and yon in a breathtakingly tight dance routine choreographed (in 24 hours, apparently) by Blanca Li, a fierce-looking but funny Spanish woman who was sitting at my table quietly chatting with Pedro Almodóvar’s costume designer Paco Delgado one minute and whirling through space like a dervish the next. But in amidst the physical frenzy, there was the elegantly precarious image of Shalom, Amber, and Yasmin parading around the room on catwalks improvised from chairs placed under each foot as they took a step.

“Something big” it was, indeed. And thrilling and surprising. Even Simon Le Bon had no idea what his wife was about to do. It was all a remarkable testament to timing, pluck—and the remarkably pliable properties of Stella’s eveningwear.
