Philo joined the house of Chloe in 1997 as first assistant on its ready-to-wear and moved to Paris. In 2001 she was appointed creative director of the label, taking over from Stella McCartney – who had taken on Philo as her design assistant at Chloe. In October of that year, Philo presented her first ready-to-wear collection for the house and in 2002 launched Chloe’s accessories line. In 2005, Philo was honoured with the British Designer of the Year accolade by the British Fashion Council. During her reign at Chloe, the label was transformed into a luxury global brand, winning critical and commercial acclaim for both its ready-to-wear and accessories offerings. Philo resigned from Chloe in 2006 and moved back to London. During this time she had her second child. After a break from the industry, Philo was appointed creative director at Celine and made board member of Celina SA. Of joining the label, she said at the time: “It will be whatever I make it for the time I’m there.” She presented her debut pre-spring 2010 collection in June 2009 and her full spring/summer 2010 collection in October of that year.
Philo lives and works in London with her husband, gallery owner Max Wigram, and her two children.
