And luckily Williamson has managed to hold on to all the holiday souvenirs he's picked up along the way: the intricate mirrored embellishments, the blue lagoon hues, Peruvian mountain tribe tassels and geometric Mayan patterns. They were all there today, a technicolor explosion of Williamson's trademark tools. He'd based the collection on the Holi festival in India - a raucous street party where revellers fling paints and powders at each other.
Williamson's girl is far too glossy to participate in such a thing, but she certainly looked the part in ombré knitted jumpers and draped silk party dresses. But Williamson knows his client has moved on from the glamorous bohemian look he made his own over the last decade. He's modernised by adding digital print suits, dip-dye blazers and nip-tuck dresses that are almost work appropriate.
