Gok's Fashion Fix

The Sex and the City girls provided the inspiration for the catwalk theme this week. Gok Wan took on the might of the designer labels in a catwalk face-off; pitting himself against the most powerful buyers in the fashion business to present clothes Sarah J-P would be proud to wear with a high street budget £200 per outfit. It's a tough challenge, but Gok believed that by customising high street clobber and with the right styling know-how, anyone can transform a basic outfit into a jaw-dropping style statement. Did the studio audience agree when it cames to the final catwalk showdown?

Fashionista Alexa Chung managed to score a ticket and backstage access to one of the most exclusive events in the fashion calendar: Chanel's haute couture collection for autumn/ winter 2008. Not only that, but she persuaded the notoriously publicity shy Karl Lagerfeld to open the doors to his Rue Cambon apartment - once the residence of Coco Chanel - to share his private sketches with her. Alexa then lives out every girl's dream, raiding the rails of Chanel's flagship store! Can she cut it as a Parisienne chic chick?

Alexa also road-tested the fibre making a fashion come back: polyester. No longer a scratchy sweat-inducing material, it's quietly undergone a sly rehabilitation, aided by Japense design mavericks Rei Kawakubo of Commes des Garcons and Issey Miyake. The effect has of course filtered through to the high street. Alexa Chung's fleet of flight attendants, who wear polyester every day, put the latest designs to the test.

Meanwhile, Gok spent an afternoon with glamorous goth Kelly Osbourne and her delicious designer wardrobe. Plus, there's a game of 'squeeze into these' - when one lucky audience member us challenged to squeeze into one of Kelly's much loved dresses in ten seconds to win a chance to walk away with it. Gok also continues his search for a style icon as his travelling catwalk roadshow hits the UK's city streets.
