Thrifty Kate loves wearing her white and gold Alexander McQueen gown for special occasions, while Sophie Wessex regularly dons her go-to Emilia Wickstead jumpsuit to take on the cold weather.

The Duchess of Cambridge
Attending the BAFTAs back in February, Duchess Kate looked stunning in a white and gold evening gown designed by her favourite label - Alexander McQueen. As guests at the BAFTAs were encouraged to rewear an outfit or a sustainable alternative, The Duchess honoured this by wearing one of her favourite dresses, which she first wore to a state dinner in Malaysia on the Cambridges' diamond jubilee tour in 2012.
