>> Winter white came out to play this week — much to our pleasure. See who chose the snowy hue — and who chose otherwise — in the slideshow.

>> After the great unveiling yesterday during a press conference, Mario Sorrenti's "unsexy" version of the Pirelli calendar — for 2012 — was celebrated last night at the Park Avenue Armory in New York. Six of the calendar's 12 models were in attendance, joined by Sorrenti's family, Valentino Garavani, Vera Wang, and more.

>> In honor of their upcoming Versace For H&M collaboration — in stores and online Nov. 17 — the two brands pulled together three events in one last night at New York's Pier 57. Through a gilded hall of mirrors, designers (Anna Sui, Joseph Altuzarra, Christopher Kane), supermodels (Linda Evangelista, Helena Christensen), and other such notables (Uma Thurman, Chloe Moretz, Nicki Minaj, Prince) were swept into a dark room framing a serpentine catwalk, on which Versace favorites like Abbey Lee Kershaw, Natasha Poly, Lindsey Wixson, and Daphne Groeneveld wore black leather headscarves, heavy kohl, and stomped to speaker-pumping music.

Cue the next: After her runway bow, Donatella Versace gestured guests to follow her into a green-lit, disco ball-hung room covered in oversized palm tree wallpaper. Minaj took the mic — dressed in Versace for H&M, of course — and inspired Alexander Wang to sing along in the audience to every song. Much to Donatella's pleasure — and Natasha Poly's, who sat on the shoulders of a friend so she could videotape the set on her phone — Prince was up next on stage. Versace fist-pumped when Prince gave her a shout-out, clapped above her head . . . and that was before his encore of "Purple Rain."

Finally, the last of the three-prong event: crowds that had been lining up before Prince even took the stage were unleashed into the shopping area. As Style.com notes, "Many of the women in the crowd made beelines for the collection's men's clothes."

>> The first of Carine Roitfeld's Fall 2011 campaign images — starring herself and her children — were released earlier this week, and now a couple more have appeared, showing Natasha Poly and '60s supermodel and Avedon muse China Machado. Still forthcoming are Mario Sorrenti-lensed images of Victoire de Castellane, Dasha Zhukova, Noami Campbell, Marie Amelie Sauve, and more.

Barneys plans to release a new "Carine's World" campaign image each day online at The Window until Sept. 2, when the images are unveiled in the store's windows. Also promised in the lead-up: the premiere of the campaign video.

>> The Fall 2011 campaign parade continues: Arizona Muse was on set for Alberta Ferretti yesterday, as were Valentina Zeliaeva and Magdalena Frackowiak for Ralph Lauren (left).

Raquel Zimmermann recently confirmed: "I'll be in the Lanvin campaign which was shot by photographer Steven Meisel, but I can not describe how it was, total secrecy until the campaign out!" And Roberto Cavalli is reportedly employing Natasha Poly, Mariacarla Boscono, and Karen Elson to be shot by Mert Alas and Marcus Piggott and styled by Panos Yiapanis.

After Gwyneth Paltrow was spotted leaving Coach headquarters recently with Reed Krakoff, meanwhile, rumors have been fanned that the actress might be a new face for either Coach or Krakoff's Coach-funded eponymous label.

This week, the last of Fashion Week brought models and celebs to Paris, while other Fab faces we love stepped out for premieres and press dates. As you'd expect for the Parisian style gatherings, looks were impeccably chic and some fabulously fashion-forward. We spotted Natalia Vodianova looking relaxed and pulled-together in stripes and shorts, Natasha Poly and Jennifer Aniston going sheer, and Mila Kunis rocking a creamy white suit. It's an inspired group of styling — click through to see the 10 celebrity looks we're gushing over this week!

H&M is no stranger to sustainable clothing, but this April it's going all out by unveiling a brand-new line called Conscious Collection. As you guessed it, it incorporates eco-friendly fabrics like organic cotton, Tencel, and recycled polyester. "It's not just about organic cotton any more, the possibilities for creating a complete fashion statement with eco smarter materials are huge now. By designing recurring Conscious Collections we have the opportunity to show in a variety of ways what's possible using more sustainable fabrics," said H&M's Head of Design Ann-Sofie Johansson. And don't worry, style nor price has absolutely not been sacrificed; romantic pieces — $15 up to $60 — meld with minimalist colors for a must-have collection, modeled here by Fab favorite model Natasha Poly.
