Sweat a little chicer on your next workout, thanks to Mara Hoffman. The designer rolled out her debut activewear line yesterday with a short film, coinciding with the launch of a new website. First, the clothes: The gym-ready threads, which include leggings, ponchos, sports bars, and jumpsuits, ward off burns with SPF 50. The film stars Juliette Lewis dancing in the desert in the stylish workout-apropos pieces, and was directed and choreographed by Ryan Heffington; it was shot in Lancaster, Calif., outside L.A.
