American designers Pookie and Louisa Burch come from solid fashion stock as the daughters of retail mogul Chris Burch, and former stepdaughters of designer Tory Burch.

The sisters are now out to make a name for themselves in their own right, having launched sportswear label Trade Mark earlier this year. Their first collection was described by Vogue as 'timelessly elegant, classic and understated', and the brand has swiftly opened a flagship store in New York's SoHo selling its men's, women's, jewellery and accessories collections.
