Waris Ahluwalia

Arizona Muse, Carey Mulligan, Poppy Delevingne, Teresa Missoni, and Waris Ahluwalia were among those who made the trek to Switzerland this past weekend for ASMALLWORLD's third annual Winter Weekend getaway. And though it may have been frosty on the slopes outside the Gstaad Palace Hotel where the weekend's festivities took place, there was plenty on the docket to keep guests toasty.

On Friday evening, the crowd kicked off the fun with a champagne cocktail and diamond hunt. The big winner of the evening was Tali Lennox, who, clad in a two-toned leopard-print minidress, ended up winning the grand prize: a glittering pair of Bucherer diamond hoops. The next day it was off to the lifts, where Jessica Joffe and Lily Kwong showed off their best cold-weather getups (no puffy snowsuits here) while Muse frolicked with son Nikko in the snow before joining the rest of the crew for a fondue feast.

And that wasn't all. Saturday evening's black-tie charity gala hosted by Mulligan had everyone from Harley Viera-Newton to Harvey Weinstein in high spirits — especially when singer Alysha Umphress took to the stage for a surprise performance.

Highlights from the weekend, here in the slideshow.

>> It's no secret that Waris Ahluwalia is into craftsmanship. The jewelry in his House of Waris line has always been made using traditional techniques, with everything — right down to the chains on the pendants — fashioned completely by hand. It should come as no surprise then, that Ahluwalia's debut scarf collection employs that same dedication to history and artisanal techniques. Superfine cashmere is hand-loomed and hand-embroidered in a precise honeycomb "Kundun" pattern, handwoven silks and gauzy silk-cotton are batik-dyed, block-printed, hand-dyed, or silk-screened, and hems are all neatly finished by hand. It's not just the attention to detail or the heirloom fabrics that make this new collection of scarves so appealing, however — it's also the gorgeous color combinations and striking graphic patterns. Though meant to be unisex (or, as Waris says, "We don't believe in unisex, just more sex"), it's easy to imagine these pretty prints and super-soft fabrics evolving into a collection of dresses, skirts, and blouses. Waris's next project, perhaps? It's a suggestion the designer seems to have heard before, but if it's in the works, he's not talking. When pressed, his answer is a shrug, a wry smile, and a quiet: "I hope not."

>> The second installment of Swedish magazine Intermission is jam-packed with interviews: Gaia Repossi, Isabel Marant, Joseph Altuzarra, Tabitha Simmons, Waris Ahluwalia, Victoire de Castellane, and Vogue Paris art director Johan Svensson among them — and all are translated from Swedish into English at the back of the issue.

John Scarisbrick photographed and Keegan Singh styled the two covers — one with Hanne Gaby Odiele, and the other Vanessa Traina, who inside talks to Stephanie LaCava about going to high school with Alexander Wang ("He used to cut up these vintage jeans and make us denim skirts. I still have them — and he’d make us T-shirts.  We used to place orders every season with him."), consulting for Joseph Altuzarra ("Our relationship is different than most because Joseph and I are so close.  As friends, we hang out at least four times a week."), and her boyfriend, Chad Muska ("I was with some girlfriends and he was with a friend of one of my girlfriends and we met at a restaurant one night in LA.  That was eight years ago and it slowly evolved into a relationship.  He’s a street skater. We live together in the West Village, but he also has a studio in Union Square.  He’s always been into photography, but he’s been playing around with it a little more and doing some large-scale work, a mix of photographer and painting.  I have his pictures hanging in our bedroom.  It’s a photo series he did of Kate Moss manipulated and painted different shades of pink.").
