The 34-year-old showed off her shoulders in the mesh dress and allowed her long loose waves to flow on each side. Kate accessorized with delicate pink heels.

Kate also mingled with artists including Grayson Perry, Michael Craig-Martin and Antony Gormley at the event, which was hosted in the museum's central Hintze Hall.

Around 370 guests from the arts and culture sector attended the dinner, with "Dippy" the dinosaur - the museum's famed Diplodocus skeleton – providing a breath-taking centerpiece to the event.

Kate last carried out an engagement at the Natural History Museum in October 2014 when she presented Carlos Perez Naval with the Young Wildlife Photographer of The Year award.

However, Prince William's wife also visits the museum in her private time. She was famously spotted at the iconic tourist attraction with her son Prince George in October last year. The pair were spotted exploring Hintze Hall, which houses the 292-bone cast of a Diplodocus dinosaur skeleton.

Kate has long been passionate about painting, photography and the arts. She graduated from the University of St Andrews in 2005 with a 2:1 in History of Art. It was there that she met her future husband Prince William, who enrolled on the same degree before switching to Geography.

After joining the royal family, Kate chose to support charities and patronages that reflect her arty interests. She is patron of The National Portrait Gallery and The Art Room, a charity that works with children to increase their self-esteem, self-confidence and independence through art.
