>> Sarah Jessica Parker, who joined Halston in January 2010 as the president and chief creative officer of the Halston Heritage contemporary label (and simultaneously took equity in the company), is no longer involved with the brand, Vogue reports. In Parker's August 2011 Vogue cover story, writer Eve MacSweeney notes that her Halston "relationship recently came to an end." Parker was still working with Halston as recently as late April, but at the time it was also suggested that the label was cash poor and could be sold again. [Vogue]

>> Originally set to debut in July, and then August, the premiere date of The Rachel Zoe Project season four just got moved once more: It's now hitting Bravo on Tuesday, Sept. 6 at 10 ET/PT. The first episode is summarized, according to the release, as such: "In the season premiere, Rachel Zoe, Inc. is growing exponentially, and so is Rachel’s family. With a baby on the way, Rodger [Berman, Zoe's husband] looks for a bigger house, while Rachel sets her eyes on launching her new fashion line. After an Elle magazine photo shoot with her hubby, Rachel and Rodger jet off to a round of interviews for potential new junior stylists to replace Brad [Goreski, Zoe's former assistant]. Hoping she’ll slow down and take it easy, Rachel tries to manage it all leaving Rodger concerned for her health and well-being." A trailer for the season can be seen here.

>> Tilda Swinton has played muse for Viktor & Rolf and Haider Ackermann — she met both, as well as Alber Elbaz, Stefano Pilati, Phoebe Philo, and Raf Simons (who designed her wardrobe for the 2010 film I Am Love) — through her close friend Jerry Stafford, the creative director of a French production company, who she works with in place of a stylist. “He’s my playmate,” she says. “It’s a game, and we have great fun with it.”

Swinton cites David Bowie and her father, Major General Sir John Swinton, as her style icons, and says of working with friends on what she wears for the red carpet: “For someone to know what you need to make you comfortable, they need to know who you are. Having them make clothes for me is like being cooked for by someone who knows what you like to eat.”

For the one-sleeve black Lanvin sheath she wore to the 2008 Oscars, for instance, she told Elbaz she wanted “to attract as little attention as possible and to feel as comfortable as if I were wearing pajamas. Little did I know that the really simple, chic dress one might have worn in Paris or Berlin would stick out like a sore thumb in Los Angeles.”

Stafford also creative directed Swinton's cover story for the August 2011 issue of W (left) — together they created a mood board for the shoot.

>> LVMH has appointed Humberto Leon and Carol Lim, the 36-year-old co-founders of Opening Ceremony, as creative directors of Kenzo, effective immediately. They replace Antonio Marras, who joined Kenzo in 2004, and will show their first Kenzo collection in October for Spring 2012.

Under Leon and Lim, Kenzo is to be repositioned in the contemporary sector, with prices expected to range from 200 euros to 1,500 euros ($285 to $2,135).

"It’s great to bring this young, contemporary generation into Kenzo,” said Pierre-Yves Roussel, chairman and CEO of LVMH’s fashion division. “They’re really embracing what was the origin of Kenzo — that Jungle spirit.” Roussel interviewed a wide range of both young and experienced designers for the position, he said, but was struck by the “360-degree vision of the fashion industry” Leon and Lim have. He added that Marras had been “respectful of the heritage of the brand . . . What we need now is something which has more energy, which is looking forward in terms of addressing a new generation.”

While the pair are not trained as designers, they expect to “build an exciting team” of designers to realize their vision for Kenzo. Leon said that while he sketches ideas, “we’ve always worked in a team community.”

They plan to continue with Opening Ceremony, and split their time between Paris and New York.
