With a new home boutique and recently launched lifestyle Web site, Jenni Kayne's audience is larger than ever. Pre-Fall found the California designer in fine form with a wearable collection that nodded to Boy Scout sportiness and forties-inspired silhouettes. Updating her signature tailoring, Kayne added slight padding to the shoulders of a double-breasted vest for a more structured look, and teamed that with a below-the-knee pencil skirt or high-waisted trousers. Other highlights here included a crisp trench and matching skort cut from a washed python jacquard, as well as a Liberty-print twill parka jacket and a belted rabbit-fur vest (priced to sell around $1,050). For evening, she showed a puddled, shirred georgette tank dress paired with a soft camel sweater, raccoon scarf, and a pair of shades. That look nicely encapsulated Kayne's approach to casual elegance, as did her new lug-sole saddle shoes and oxford heels, which will appeal to fans who already have a closetful of her best-selling d'Orsay flats.
