You would be forgiven for thinking that Thandie Newton is wearing Matthew Williamson here. After all, does she wear anything else? (I'm just jealous!) But in a surprising move, the actress was spotted at the Lavender Trust 10th anniversary bash last night in a design by Roberto Cavalli, from his A/W '08 collection. In true Cavalli form, there is a lot going on in this dress - sequins, sheer mesh, floral, there is also a touch of hippy boho in the skirt section. It is an unusual piece and one that most stars would probably steer clear of, but does Thandie do it justice?
