Life’s a ball for Paris Vogue, which marked its 90th anniversary with a hefty October issue that bowed last week. The tome bursts with special editorials and contributions. You could say its cup runneth over, much like Lara Stone’s famous assets on the cover. But we wouldn’t expect the fun to stop there, not when Paris Fashion Week is upon us. Carine Roitfeld is pulling out all the stops tomorrow night with an epic masquerade ball to fete the issue and her triumphant reign at the style bible. The party, in all its decadence, is expected to draw all who’ve appeared in the magazine on her watch—and that’s pretty much everyone. A few editorials in the issue (pictured here) give hints as to the suggested attire for the event (we hear New York jewelry designer Eddie Borgo is whipping up a few exclusive masks). Expect this one to go down in the history books. Bon anniversaire, Paris Vogue!
