Before you come over all Working Girl 2, a word of warning: this season's power dressing is not simply to be confused with the Eighties revival.
It's influenced by the decade undoubtedly, but is also grounded in couture, tailoring, rock chicks and minimalism.
This season's power ethic borrows from all trends but is slave to none.
The most important rule is simplicity: wear pieces you like, that make you feel in control – and that make others not a little bit uncomfortable.
Take French Vogue-editor chic as your starting point and hone a style that is smart but cool, relaxed but still bang on the money.
