Duchess of Cambridge turns up to the Queen's birthday celebrations in £3400 D&G dress

Kate Middleton kept it lowkey chic in a £3400 D&G dress as she attended the Queen's 90th birthday celebrations at Windsor castle. The centrepiece of her outfit on the night however was a red £49.99 Zara Jacket which she accessorized with diamond drop earrings. Thanks to the Kate Effect, the expensive dress has sold out online.
