That's why the sartorial movement made InStyle’s annual Style 100 roundup featuring all the looks, trends, and pop culture moments that defined the past year. Four Athleisure Outfits to Wear for Any and Every Occasion Designer's collections (like those from Baja East, Brunello Cucinelli, and Net-a-Porter's new shopping portal for designer workout gear called Net-a-Sporter) weren't the only place we saw chic sportswear take over: In the world of pop culture, Johnny Weir and Tara Lipinski gave new meaning to the term "color commentators" at the Sochi Olympics with a star-making turn rink-side (they practically edged Scott Hamilton right off the ice). Meanwhile, Roger Federer debuted a tennis-shoe version of the Air Jordan—tagged with his own RF logo—at the U.S. Open, as Michael Jordan watched from the stands.
