Get the look: Kate's electric blue dress
The Duchess of Camrbridge stepped out today, as the sun finally made an appearance, in a pretty electric blue dress by Stella McCartney. She paired the brightly coloured dress with simple black Prada heels and a very Olympic-inspired, gold hooped necklace. The look was finsihed off with her trademark glossy, blow-dried hair.
Kate was visiting the Road to 2012: Aiming High exhibition at the National Portrait Gallery, where they were unveiling a portrait of the Queen.
