By Sharnaz Shahid

The Duchess of Cambridge looked incredible as she arrived at the Natural History Museum for the opening of the museum's spectacular new Hintze Hall, on Thursday evening. Turning heads as she passed by, the royal oozed elegance in a short-sleeved knee-length Preen by Thornton Bregazzi blue dress which retails at $683.

She completed her look with a pair of black Prada sandals, which she first wore during the royal tour of India and Bhutan, and a gold and purple clutch.
