As at least the Baron and the Senator are aware, Net-a-Porter, the online women's emporium of high fashion, has launched a "brother" Web site, Mr. Porter. Mr. Porter offers designer clothing and accessories by labels Maison Martin Margiela (mmmm), John Lobb, Lanvin, and Richard James, along with old standbys YSL, Paul Smith, and Gucci. The site comes complete with tips on how to "please" a woman (date ideas, gift suggestions, and wardrobe essentials) and on how to achieve the savoir-faire and aesthetic of certain male style icons (Dylan, Jagger, Gianni Agnelli, Lord Glenconner, Jean-Paul Belmondo, and the inimitable Lapo Elkann). Whether you're looking for a Charvet pocket square (and who isn't, really?), an A.P.C. le mariniere tee, or Rick Owens leather jacket (delish), Mr. Porter has just the thing to up your personal sartorial ante.
