The former head designer of Ralph Lauren’s sportier RLX line, Tim Coppens knows a thing or two about keeping athletic clothing classy—afterall, Ralph Lauren wouldn't do sport any other way. To make sure things stay dapper, Coppens has complemented windbreakers and geometric leggings with menswear staples in staid black, and grey two-button blazers are cut to perfection and then paired with banded sweat pants. Buy Coppens' entire collection, and you'd be prepped for cocktail hour and 5k runs alike. (via The Moment)
