WARM AND FUZZY: Upper East Siders Gigi Mortimer and Courtney Moss have teamed up to create a line of accessories just in time for the fall chill. Called Glamourpuss NYC, the collection of Rex rabbit fur neck warmers and fox fur mittens — which retail for $199 and $315, respectively — will arrive at boutiques such as Kirna Zabête and Calypso beginning later this month. Items are already available for purchase on the company’s Web site, glamourpussnyc.com. The fashion-savvy duo — Mortimer designed accessories for Ralph Lauren and Vera Wang, while Moss has worked in public relations at Yves Saint Laurent and Giorgio Armani — came up with the idea for the line while suffering through their grade school sons’ early-morning hockey practice in Central Park. “Everyone there was pale and ugly and miserable,” recalls Mortimer. “And we thought, ‘Even though it’s cold, why can’t we be glam?’” Friends Kelly Killoren Bensimon, Stephanie Clark and Elizabeth Lindemann appear in the Glamourpuss look book, but Mortimer knows she is her own best advertisement and already has been spotted wearing her neck warmers around town. Presumably, Mortimer also will be wearing her wares when she and Moss host an official launch party at Calypso’s Madison Avenue outpost on Oct. 29.
