Fashion Week

Kate Moss donned a wig and walked the runway at the Louis Vuitton Fall 2013 fashion show in Paris today. Fashionable celebrities Naomi Watts, Elizabeth Olsen, and Jessica Chastain sat front row at the show to watch Kate make her return to her old stomping ground. Kate's husband, Jamie Hince, and daughter, Lila Grace, also made the trip over the Channel to watch the model mom work her stuff. The Louis Vuitton show wasn't the only big fashion news Kate was working on — Kate was named "fashion royalty" by The Sunday Times yesterday, the same day that she attended Carine Roitfeld's CR Fashion Book Issue 2 launch in the City of Light.

Kate's see-through Louis Vuitton dress was surprisingly less revealing than her recent nude photo shoot with Rihanna for V Magazine, which featured the singer and the model in alternating topless poses.

January Jones, Zoe Saldana, and Renée Zellweger lent their Hollywood support at Miu Miu's Fall 2013 show in Paris today. January channeled her Mad Men character, Betty, when she dropped by the event in a retro hairdo and a Miu Miu ensemble. Meanwhile, Zoe and Renée sported black outfits and chatted with Rebecca Hall while sitting front row. Renée and Zoe have more in common than just their taste in designers since both women have previously dated Bradley Cooper.

It's a good thing that January is getting into the '60s spirit, as filming for Mad Men season six is still under way. Jon Hamm and John Slattery filmed scenes for the new season of Mad Men outside a hotel in LA yesterday while January was in the City of Light. Fans will be able to catch the show soon as a new Mad Men promo was released earlier this week, calling the April 7 premiere the "affair of the year."

In glancing back at the many Miu Miu presentations, one thing is certain: designer Miuccia Prada has a thing for the eyes. Every season, her team seems to find new ways to bring light to this stunning feature. While the shoes may be the brand's shining glory, these top makeup palettes could rival any fancy footwear.

Earlier today, the most anticipated ready-to-wear show of the season kicked off at the Grand Palais in Paris. Chanel reigning King of the world (or so we must infer from the giant globe in the centre of the room), Karl Lagerfeld was there to greet his famous fashionable fans that included Vanessa Paradis, Leigh Lezark, Alice Dellal, Anna Wintour, Livia Firth, Milla Jovovich, Princess Caroline of Hanover, Jessica Chastain and Clotilde Hesme.

Kirsten Dunst and her boyfriend, Garrett Hedlund, attended the Saint Laurent runway show during Paris Fashion Week today. The couple sat front row next to Vogue editor Anna Wintour and were also seated near Jessica Chastain and Salma Hayek's husband, Francois-Henri Pinault. Kirsten and Garrett touched down in Paris over the weekend and will likely be checking out more Fall '13 collections before the festivities wrap up on Wednesday. Kirsten is also gearing up for the release of her latest film, Upside Down, which costars Jim Sturgess. The two play star-crossed lovers in the sci-fi romance flick, which is scheduled for a limited theatrical release on March 15.

Over in Paris this morning, celebrities like Twiggy, Jessica Alba, Nicole Richie, Natalia Vodianova, Marianne Faithfull, Anna Wintour, Nancy Shevell, Sir Paul McCartney along with U2 lead singer Bono and his wife Ali attended the Stella McCartney Autumn/Winter 2013 Ready-to-Wear show. It looks like Jessica Alba and Nicole Richie got cosy in the city of love and the elder music set sat together and chatted. The clothing looks amazing in the photos as modeled by Cara Delevigne and Karli Kloss just to name a few wearing purples, blacks, whites and greys. Whilst Sir Paul and his bride arrived in the appropriate coloured tops, they both chose light coloured denim on the bottom. Hopefully Stella is as proud of the collection as we are excited, after all, she did get a standing ovation from this critical fashionable front row.

At Saint Laurent Paris (formerly Yves Saint Laurent), the history of runway beauty runs the gamut, swinging from androgynous to glamorous and right back again. The results are almost always unexpected, yet still very YSL. Click through to see some of the best looks from past runways of Yves Saint Laurent, as well as the newly renamed Saint Laurent Paris.

The House of Givenchy was opened in 1952, with Audrey Hepburn in place as one of designer Hubert de Givenchy's original muses. While the brand still captures the chic, feminine moments of the midcentury ideal, today's collections have an edge. Models are frequently done up in overstated eye makeup with slick, slightly waved hair. See some modern-day interpretations of the fashion house's forward-looking approach.
