Cashmere sweat( er)

The rich-girl uniform gets a sporty spin this season. These luxe layers won’t be as breathable as your Dri-FIT , so save them for yin-yoga class or a post-workout green-juice run. Better yet, wear them 24-7 and pretend like you just came from the gym. We love the new sportswear line Kit and Ace (the brainchild of JJ Wilson, son of Lululemon founder Chip, and Shannon, former head Lululemon designer and Chip’s wife). The ace up its sleeve? Technical Cashmere: a soft yet durable blend you can throw in the wash. Bates Bra, Kit and Ace ($48, kitandace.com)
