When beautiful, skinny women find the ultimate object of desire, they pounce and things can get ugly. It's true on "The Bachelor" and it's true when the latest denim arrives at this boutique.

Lisa Kline was a girly-fashion pioneer until other stores around town started to copy her girly formula. Then she got wise—and got sexy. The store always feels like Friday night, with LA's most nubile young women buying dresses, jeans and tops for a never-ending round of premieres, parties and clubbing. Body-revealing fashions are the signature here, from both established designers (many launched by Kline, like Frankie B. and Juicy) and newcomers like Tiffany Alana. The twentysomething Alana, who stitches jersey skirts on her grandma's sewing machine, had her cotton skirts and dresses hanging loose over Jewel's butt—and stretching across J. Lo's—a few months after meeting Kline. Britney Spears buys clothes here by the bagful; Eve pulls up with her bodyguard. All hotties a size 8 or below are welcome here, too.
