While Wednesday was all about shopping for Kate, yesterday she got down to business looking equally fashionable leaving a meeting at the Topshop offices with Phillip Green. Her work for Topshop is always in demand, but it's not just her designs that are so sought after — a Warhol-esque portrait of Kate by the artist Banksy is expected to fetch at least $146,000 at auction later this month. Despite the recession, Kate's stock keeps going up in value.
