I have received confirmation that Kate’s hat at the Epsom Derby was made by hat company Whiteley:
The hat is called “434/318” and my source believes Kate purchased the hat from Fenwick’s of Bond Street. I have also been told that Kate wore one of Whiteleys hats to a friend’s wedding in February.
The hat is from the current Spring 2011 Whiteley range, and is made from Parisisal straw.
Kate chose the hat in the “Cappuccino” colour. Whiteleys have recently delivered more of this colour as well as Black, Navy and Linen versions to Fenwick of Bond Street, London.
