A NEW CONTRIBUTOR: Chloë Sevigny has signed on with Elle U.K. as a "style adviser." Beginning with the March issue, the "Big Love" actress will regularly pen a column as a fashion expert, answering readers' fashion and style questions every month. The issue also includes a piece from the Wall Street Journal's new lifestyle magazine editor, Tina Gaudoin, exploring fashion's new eco-awareness. Sevigny is on the March cover, which hit newsstands Wednesday. — A.W.

BIG BROTHER: Be careful when chewing gum, yawning or indulging in any other eyebrow-raising activity during Mercedes-Benz Fashion Week — someone somewhere in the world could be watching. On Friday, American Express will launch the American Express Fashion Network, an online service that will bring the live action at the Bryant Park tents to americanexpress.com/style. The company has set up Webcams throughout the tents and will offer live streams the entire week, from runway shows to backstage views and other tent areas. Viewers will have an option of streams to watch, and the network also will provide special interviews with designers and industry executives, fashion forecasts and trend reports. Robert Verdi is the network's official host, with Roshumba Williams serving as a special correspondent.

"The American Express Fashion Network enables designers and industry insiders to highlight the shows, share their personal views and gain meaningful visibility with consumers everywhere who are passionate about fashion," said Jessica Igoe, director of sponsorship marketing for American Express. The live stream will run throughout the week, and clips will be available for viewing afterward. American Express also plans to syndicate videos to other Web sites and is posting the Fashion 360 Presented by American Express program with highlights from the network on YouTube. — Marc Karimzadeh

PUTTING ON A SHOW: The precious few red-carpet events in light of the writers' strike has cut into magazines like In Style's bread and butter, so the fact that the Grammys were allowed to go on must seem like a godsend. Accordingly, the magazine is putting together a fashion show for celebrity musicians-turned-designers in Los Angeles next week to kick off the festivities. Curated by the magazine's fashion director, Hal Rubenstein, it will feature spring apparel by Beyoncé and Tina Knowles' House of Deréon, Sean Combs' Sean John Women's, Jay-Z's Rocawear, Jennifer Lopez's justsweet, Jessica Simpson's Jessica Simpson Collection and Justin Timberlake's William Rast, with the sponsored presences of Paul Mitchell, Cover Girl, Steve Madden and Le Vian. (Though this is a single event that will be covered both in the magazine and other venues, comparisons to Condé Nast's "Fashion Rocks" special are perhaps inevitable.) — Irin Carmon
