The Duchess of Cambridge wore one of her favourite designers...

Kate Middleton delighted royal fans on Tuesday when she made a surprise appearance at Wimbledon. The Duchess of Cambridge was accompanied by her husband, Prince William, and looked absolutely stunning in a blue polka dot dress.

The frock is from one of Kate's favourite fashion designers, Alessandra Rich. The Duchess wore a similar polka dot dress from the same designer when she attended Royal Ascot back in June.

The bright blue number features stylish puff sleeves, a belted waist and a smart, pleated front. Kate paired the dress with a white handbag and matching white heels, accessorising with pearl earrings.

As for hair and makeup, the Duchess wore her brunette locks in a sleek, straight style and went for a subtle smokey eye and a pink lip. If you're wondering what lipstick she might have used, don't forget to check out our guide to Kate Middleton's favourite beauty products.
