>> Ivory, black, and nude reigned queen amongst this week's best looks. See who's wearing which — and where — in the slideshow.

>> On the heels of the throwback shimmery, animal-printed Holiday 2011 collection, Versace for H&M is back for another round. Donatella Versace also developed a Pre-Spring 2012 collection for H&M — complete with fruit prints — that will be available exclusively in countries with H&M online sales (currently only Sweden, the United Kingdom, Germany, Denmark, the Netherlands, and Norway) from Jan. 19. As for US citizens — since H&M isn't launching an online shop in the US until Fall 2012 — the best source for nabbing the collection will likely be eBay.

>> The season's most versatile piece walks the line between dressy and dressed-down — and doesn't compromise on comfort. From the slim, belted styles of Fendi and A.P.C., to the fit-and-flare versions on offer from Tibi and Bensoni, there's a sweater dress for every mood. Pair with ribbed-knit tights and platform booties for a chic day-to-evening look, or, go for glam with ankle-strap pumps and statement jewels.

>> The long-awaited Gaga's Workshop is now officially open at Barneys in New York.

Lady Gaga was on hand last night — in a custom Chanel couture dress, specially designed by Karl Lagerfeld for the occasion — to cut the ribbon and welcome inside the likes of Prabal Gurung, Carolyn Murphy, and Alexander Wang.

The store's fifth floor is completely transformed until Jan. 2, filled with chocolate Alexander McQueen armadillo shoes, studded press-on nails, and candle replicas of Gaga’s head that cry when lit. Inflatable cartoonish sculptures and taxicab wraps promoted the opening around the city, and Barneys's windows, too, have been Gaga-fied. "My favorite window I think is [the] one window that looks like my boudoir and it's covered in blonde hair," Gaga told WWD. "It's gorgeous."

Despite all the expenditure, Barneys expects to break even on the promotion, its chief executive Mark Lee said. Twenty-five percent of the workshop's sales will go to Gaga's new Born This Way Foundation, which focuses on youth empowerment; Lee added that the store hopes to raise over $1 million for the cause.

>> Next month, Valentino will open his archives to the world. Using 3D technology, the Valentino Garavani Virtual Musuem — found at Valentino-Garavani-Archives.org — catalogs over 300 dresses from Garavani's five decade-long career, including Julia Roberts's Oscar dress and the couture dress Jackie Kennedy wore to wed Aristotle Onassis.

The site, which officially launches Dec. 5, will also feature over 5,000 images and 95 fashion show videos. Giancarlo Giammetti, Garavani's longtime business partner, explains of the site's content: “Animated galleries show a life’s work, and key dresses have been photographed in 360 degrees. Click on them and they revolve to show every line and stitch. Click again and discover the history of the dress, who wore it where and when, see it in the amazing campaigns that we created for the collections in the late 1960s, 1970s, '80s, '90s . . . move through to other spaces leading off the sunlit courtyards under the Roman sky to new galleries full of photographs of friends, models, drawings, animations, videos.”

Garavani adds of the project: “I see it as part of my legacy. I am happy that thousands of students, young designers and fashion people will be able to see and study my work in every aspect of it, and in a manner easy and accessible for the younger generations. But it is also important to remember things of the past, to review the fashion that has shaped our lives. I would call it ‘Future Memory.’”

>> Although there were rumors that Gisele Bundchen shot the Spring 2012 Givenchy campaign last month in Jamaica, it seems that was not the case. Bundchen was snapped with Riccardo Tisci earlier today, shooting the campaign on the beaches of Barcelona. We've got a few snaps from the set; this may not be the end of Bundchen's Spring 2012 campaign streak — the model, who is already headed home to Brazil, is also said to be in the upcoming Versace campaign.
