Philo is every girl's favourite designer. She was Stella McCartney's right-hand woman at Chloe, before taking up the reins herself and kitting us out with everything we needed, just when we needed it. After briefly stepping away from the fashion limelight she returned triumphant to take up residence as creative director of Celine, and each of her collections has had every style setter furiously making their shopping list. We're itching to see what she has in store for us next.
Signature style: Chic sportswear-influenced minimalism
Best buy for A/W 2011: A pair of two-tone leather and wool trousers.
