Meet The New Pantsuit: What Would Hillary Wear?

Is it fashion's passion for the 1980s? Or just a strong statement from women who have had enough of girly dresses?

Giannini's rock chic pantsuit is also a subtle challenge to an era of celebrity gowns.

But this time, it is a taut boyfriend jacket and slim trousers worn with hands plunged into hip pockets.

International designers creating this strong trend include Stella McCartney, who has always made mannish tailoring a counterpoint to the pretty woman. Other female designers, from Hannah McGibbon at Chloé to the iconic Sonia Rykiel, have also come up with interpretations of the boy-girl thing.
