And Rihanna exposed quite a lot of naked butt skin at the Met Ball.

The biggest fashion stories of the week, save for the one about how we received a big block of cheese in the office (which was actually very awesome).

TGIF, fashion bunnies! Let's finish up another work week with a little fashion news, shall we? Proceed.

Execs hope new creative director David Koma will take the house's ready-to-wear in a more wearable, sellable direction.

From Bjork's infamous swan ensemble to sexy creations by Thierry Mugler, The Simpsons' beloved matriarch works some of the most memorable looks in history.

Claude Montana is back. Sorta. According to WWD, reclusive '80s powerhouse designer Claude Montana will have three designs featured in Eric Tibusch's couture show this evening. Montana's presence was teased as a mere "C.M." on the invitations. The designer, who hasn't had a show since 2002 and whose third hit on Google is from 1996, is most famous for the bold, structured, and colorful looks which helped define '80s fashion.

Who better to replace the void left by Nicola Formichetti at Mugler than Manfred Thierry Mugler himself? Following an announcement earlier this month that Formichetti, brought on as creative director to revive the Mugler fashion brand (which he did with a little help from Lady Gaga, male porn, and social media savvy) was out, comes word that the brand's namesake is returning.

Thierry Mugler has always been known as a creative revolutionary in the fashion world, and when he launched his first fragrance, Angel, 20 years ago, it was a completely shocking concept in many ways. From the weird scent to the crazy ad campaigns (and the fashion that inspired them), take a walk down memory lane with us to celebrate Angel's 20th anniversary in the US.

Following Nike's lead, Thierry Mugler has dropped Paralympic gold medalist Oscar Pistorius as the face of its men's fragrance, Amen.

Brad Pitt's Chanel No. 5 commercial is out and we have to admit it confuses us. Here are 10 other perfume commercials that also make us say, "Um, what?"

It seemed all of lower Manhattan got their freaky dressing on last night to celebrate the opening of Nicola's, Nicola Formichetti's pop-up concept store with BOFFO Building Fashion. The black-leather-filled line that snaked up Walker Street held enough silver studs to decorate a Hun army, and I counted no fewer than six people with primary-colored hair all before even entering MI-5, the uber-cool bar next to the pop-up where Thierry Mugler parfums was throwing the celebration. The outfits themselves weren't the only unusual sight. Rarely do you encounter a store in the middle of Tribeca with an interior of fractured mirrors and a giant panda in the window. But that's Formichetti for you; the Thierry Mugler designer and Gaga stylist is always mixing it up. So how did it all come about? "Boffo approached me and asked if I'd be interested in opening a store," Formichetti told us. "And I was like, 'Well, it's not like I'm not busy.'

Here at Fashionista, we spend a lot of time looking at designers' ad campaigns, especially within the last few weeks as the fall ads drop. We've even dedicated four slideshows to ranking them. After seeing the same ads in September issue after September issue, you can't blame us for wanting to find a new way to look at them. Inspired by a recent post on OC Weekly, we realized we could actually improve the fall ads using photoshop and pictures of something else we spend a lot of time looking at: cats. So, without further ado, here are 11 fall ad campaigns improved by some adorable cats.

Usually, it’s editorial shakeups that get us all confused and inspire us to create befuddling charts and guides to recap and (at least attempt to) make sense of movement within the fashion industry. Lately, however, it seems that most of the movement is taking place at big fashion houses. Whether it’s the economy or designers getting burnt-out, it seems like a top level position opens (or gets filled) every week. From Galliano's exit from Dior to Marios Schwab's from Halston (which happened so recently we didn't have a chance to include it), here’s our little visual guide to the recent ins and outs at major fashion houses.

Clarins pulled out all the stops for last night’s launch of Thierry Mugler Angel Eau de Toilette (as they tend to do for Mugler fragrance launches) and introduction of the newest Angel, Eva Mendes. They turned the first floor of the Westside highway-adjacent, Frank Gehry-designed IAC building into this cinematic, dreamlike Thierry Mugler Angel world. There were stars and comets somehow projected onto the ceiling. They even erected a gigantic comet (the same shape that outlines the perfume bottle) in the entrance that you had to walk under to go in to the event. They stamped a star on my hand when I walked in for no apparent reason. Also, I’m pretty sure the Angel scent was somehow wafting through the venue. I never stopped smelling it, even after I left, because I took the little blue Angel-scented scarf a woman suggested I tie around my wrist because it was pretty and blue. About an hour and a half into the event, Eva Mendes made her very planned and theatrical entrance. The lights went down, the music changed to Nina Simone’s “Feeling Good” and everyone stopped talking and gathered around to watch Eva walk through the giant comet in a gorgeous cream, strapless Nicola Formichetti-designed Mugler gown.
