Prince William and the Duchess of Edinburgh were seen attending a private screening of the film 'Rhino Man' in South London yesterday and royal fans can't stop talking about Sophie's stunning dress.
The Duchess of Edinburgh looked gorgeous beside her nephew in a beautiful purple and pink floral dress, which she paired with a matching clutch bag and beige Prada sandals.
Sophie's Roisin floral-patterned mini dress from Erdem retails for £1,350 on Selfridges but is on sale on net-a-porter for £945, the Express reports.
