If the late ’70s and early ’80s offered up any worthwhile trend, it was men’s wear–inspired dressing: Think silk shirts tucked into roomy trousers and finished with an oversize trench. Geared toward working gals trying to make it in a man’s world, the look communicated not only power and assertiveness but also a feminine allure (see Kim Basinger in 9½ Weeks). Three decades later, designers are bringing back the ease of it all.

It’s a casually pulled-together uniform for today’s take-charge women. Get it now with the mix- and-match pieces below.
