Marchesa brought red carpet glamour to London Fashion Week on Saturday with romantic gowns in lace and silk embroidered with exquisite floral threadwork, as Julien Macdonald unveiled a multi-million-dollar diamond-encrusted wedding dress. The luxury label Marchesa normally shows in New York but returned to its British roots for a one-off show to mark its tenth anniversary with a spring/summer collection inspired by “modern-gypsy Woodstock spirit”. US Vogue editor Anna Wintour, US film producer Harvey Weinstein and British singer Paloma Faith were in the front row as models floated past in a string of knock-out dresses in black, gold, white and fuchsia. We wanted to have an ease to the collection,” said Georgina Chapman, one half of the team behind Marchesa and Weinstein’s wife.
