Kate, Will and Harry grab their wands for a wizard day out at Harry Potter film studios experience

The Duchess of Cambridge with her husband and brother-in-law prince Harry visited the Harry Potter film studio.

Kate won style plaudits for her polka dot dress - a £38 number from Topshop, which was a stark contrast to the £1,065 Erdem deign she wore in Manchester on Tuesday.

She looks beautiful.
