Duchess Kate wears blue for National Portrait Gallery visit

Duchess Kate has been keeping a busy schedule this week.

After celebrating the scoutson Sunday and visiting a primary school in Manchester on Tuesday, she stepped out in London on Wednesday evening to attend an event at the National Portrait Gallery.

Wearing a light blue, sleeveless cocktail dress by Emilia Wickstead, the 31-year-old royal mother-to-be was there to celebrate the work of The Art Room, a charity she became patron of last year.

The Art Room uses art therapy to increase children's self-esteem, self-confidence and independence.

According to the Daily Mail, Kate met with children who were helped by the charity, as well as the staff that worked with them.

"I am a firm believer in the power of art to make a difference and The Art Room makes this on a daily basis," she said in a speech at the event.

While at the National Portrait Gallery, Kate was photographed passing by a portrait of her husband, Prince William, and brother-in-law Prince Harry. No word on if she stopped to see her own official portrait, which was unveiled earlier this year.
