EXCLUSIVE AT NET-A-PORTER.COM. The upgrade of track-style pants to eveningwear territory is one of our favorite proposals of recent seasons, and Roksanda's version is just as elegant and bold as we'd expect from the London-based designer. Tailored in England from cady, they're trimmed with cobalt hammered-satin down the legs to mimic athletic stripes. Depending on what shoes you choose, the exaggerated wide legs will elegantly pool at the hems.
