Ever the sportswear aficionado, Jenni Kayne was inspired by a mix of nautical and military elements for Spring 2014, designing a capsule of separates that play to her customers' love of preppy silhouettes with a distinctly Californian ease.

Blazers have always been a big part of Kayne's repertoire, but this season she lengthened them—a navy double-breasted version was draped over sailor-style trousers and a stripey shirt. "Everyone already has a boyfriend blazer in her closet," Kayne said earlier this week on the phone from Montecito, where she's prepping for the opening of two new namesake boutiques. "But as long as you offer a new take, people keep wanting it."

Another piece her customers are sure to want is a silk-wool housedress in a very pretty lavender verging on pink. Worn with a pair of rusty-brown loafer heels and a circle pendant necklace by Mannin, it's the perfect look for shopping at L.A.'s famed Brentwood Country Mart, where Kayne's own store exists alongside a hip juice bar and cold-press coffee shop.

There were some "ethnic influences" mixed in there too—a blazer-and-skort combo printed with a copper-and-black pattern, for example—but they were subtle enough not to detract from Kayne's straightforward vision.
