Sixties icon Twiggy heads up this fashion series which sees 100 women donating their clothes to a huge clothes swapping extravaganza. Each of the women has chosen five items from her wardrobe to be displayed in a huge purpose-built retail space where all the clothes cost nothing. There is a customising corner to accommodate all shapes and sizes, and a team of hair and make-up stylists offering all the women the chance of a glamorous makeover. Each week at the Frock Exchange, Twiggy is joined by Lauren Laverne and Grazia style director Paula Reed who help guide women towards a brand new look. Every edition of the programme features a celebrity who drops by offering up something from their own wardrobe. This time, Roisin Murphy gives one lucky woman the chance to win some Gucci heels. Plus Burberry creative director offers this season's trench coat to the swap. And 47-year-old Lynda passes on her shocking 80s wardrobe to two teenage sisters who are looking for some cutting edge fashion.
