Slatkin and Hilfiger, together with the Swiss luxury group Labelux, bought Belstaff a year ago and set out to revive the maker of technical outerwear. Their idea was to take the brand back to its British roots. To accomplish that, Slatkin hired Martin Cooper from Burberry to head up the design studio and William Sofield to create the interiors of Belstaff stores. “Bill and I had a 35-minute conversation about hangers,” explains Slatkin. “I needed someone who is as anal as I am about detail.”
