InStyle's new teen title, Your Look, is finally on stands - and on MySpace. The magazine has its own pink page where members are asked to send photos of their own personal style, and also to read articles about "where stars pick up their cute and sexy lingerie." That's where we learn that Christina Aguilera gets her thongs in a giant pink strip mall, and Ashlee Simpson has browsed through "feather trimmed panties from the British brand Myla." The best information might come from New York, where Mary Kate Olsen enjoys Kiki de Montparnasse, a naughty sex shop in Soho with beautiful silk lingerie and a small trove of upscale sex toys. The accompanying art - a cutout photo of Mary Kate, next to a gleaming case of handcuffs and pasties - is especially amazing. As a teenager, that's exactly what I wanted to know about my favorite stars, too.
