Couture Club
It's so rare for London to stage a high-wattage fashion event, the city is still reeling from the delirious glamour of Tuesday's V&A Golden Age of Couture gala. The museum's Raphael room has rarely witnessed such a whirl of amazingly dressed women, supermodel aristos, and rock royalty. Jemima Khan arrived in silver Dolce with a full-metal belt, Natalia Vodianova in Givenchy couture (five days after delivering her third child), Agyness Deyn in a draped Burberry goddess gown (a preview, she said, of Christopher Bailey's upcoming collection), and Kate Moss in fragile thirties satin (so fragile that it developed a few rips during the course of the evening and had to be customized as a short, tied-up dress). Designers came thick and fast at the Dior and British Vogue-sponsored event: not only John Galliano but also Christopher and Tammy Kane, Narciso Rodriguez, Riccardo Tisci, and Todd Lynn. Quentin Tarantino, artist Mark Quinn, and Johnny Borrell of Razorlight added to the heady social scene, but the table that attracted the most traffic was the one occupied by Prince, who held court all evening.

Royal Flush
On Wednesday, Matthew Williamson celebrated the tenth anniversary of his label with Sienna Miller, her reported beau Rhys Ifans, and Lizzie Jagger, among others, at the city's new Bungalow 8 outpost. Attendees—many clad in bejeweled creations by the designer—were still buzzing about his show, which was opened by Prince. "Where is he tonight?" asked Christian Louboutin, who claimed that he "worshipped" the singer. "They said he'd be here an hour ago." Despite being on the list, Prince was a no-show. The party, nevertheless, continued slightly past sunrise following the late arrival of Amy Sacco. Her presence got the transatlantic set, who were presumably still on East Coast time, observing that the club felt just like Bungalow in New York. Narciso Rodriguez, however, disagreed. "It doesn't feel like Bungalow," said the designer. "It is Bungalow, but on the other side of the ocean."

Hurraj, Hurraj
The same evening, Cartier pulled out all the stops for the London launch of their Inde Mysterieuse collection, the largest group of unique pieces ever created by the company. Historic Lancaster House was transformed into an Indian palace for the occasion—a feat that took 8,000 hours of work and 1,500 yards of sari fabrics. Nearly life-size topiary elephants greeted guests including Monica Bellucci, Carolina Herrera, and blue bloods HRH Princess of Kent, HH Rajmata Gayatri Devi, and the Duke of Marlborough. Turns out Prince wasn't the only royal in town, after all.
