CATHERINE, DUCHESS OF CAMBRIDGE

Before she officially joined the Royal Family upon her marriage to Prince William in 2011, the Duchess of Cambridge lent a hand to her parents’ successful business, Party Pieces. The future queen, 40, dabbled in photography and compiling catalogues to help market the company – with photography becoming a hobby she has continued since taking on the role of a senior royal. But this wasn’t the only day job the mum-of-three had. Prior to her stint at the family company, Kate worked as an accessories buyer for fashion retailer Jigsaw.
