Trending: Legs for Days

With cuts reminiscent of '70s-era boogie and 1940s subcultures (think Studio 54 meets the zoot suit craze), designers like Acne, Tom Ford, and Calvin Klein are now giving your stems some room to breathe and move. Mixing fine fabrics and sleek tailoring (and even the occasional daring pleat), these slacks will ventilate your gait while getting you into the groove. Pair them with a snug top or turtleneck, and you'll be king of the sidewalk and the dance floor.
