Clancy McCarty is something much more important than beautiful or stylish (both of which she is, too). She’s dedicated. A filmmaker, and the manager of special projects at Christy Turlington Burns’ charity Every Mother Counts, McCarty spends her working days creating programs to raise awareness of maternal mortality worldwide. Worthy, if not heavy stuff. Indeed, she's earned a little well-deserved fashion frolicking every now and then. So, what gets it done? An updated version of our personal high-school staple, the Gap sweatshirt. This one in woven wool with navy stripes is perfectly on-trend, and, dare we say it, an essential piece designed for some serious fun.
