This globe-trotting British designer celebrated his tenth anniversary in business last year, and he's slated to open his first boutique in Manhattan this June. It's probably no surprise, then, that there was a cheery optimism to his pre-fall designs, which featured brilliant colors, perky prints, and pompom embellishments. Inspired by the Ballets Russes and a Slavic classic called La Bayadère (The Temple Dancer), Williamson showcased a ballerina print. For good measure, there were also star patterns and paisleys exploded to abstraction mixed in with rainbow-hued tweeds, Aran-style knits, and rabbit fur pullovers.
