After her scene stealing appearance in the Queen’s diamonds on Tuesday night, the Duchess of Cambridge was back to earth with a bump in grittier surroundings today.

But she still stood out a mile in a new kingfisher blue dress by LK Bennett and black suede heels as she arrived to officially open The ICAP Art Room at Northolt High School in west London.

Kate has been Royal Patron of The Art Room charity since 2012. It is a national charity which offers art as therapy to children and young people aged five to 16 who are facing challenges in their lives.

Its programme helps youngsters to grow in self-confidence and self-esteem and, hopefully, engage in their education.

With studios in Oxford and London, Northolt High School has been chosen as the charity’s seventh venture as it is a school serving a diverse population, Daily Mail informs.
