The Duchess of Cambridge's style icon status means her every move is scrutinised by fashion followers keen to get the same look.
And now they can do just that with a new app which allows fans to copy Kate's style.
Founded by former actress and huge Kate fan Helen Barclay, Kate's Style List is designed to help users shop the brunette beauty’s iconic looks.

Priced at just 69p, the app lists exactly what the royal was wearing to any particular event, who designed it, and where users can buy an exact copy.
"I spend a lot of my time trawling fashion websites and looking at the designers’ shows online so I can identify her pieces," Helen told the Daily Telegraph.
"I also follow a lot of fashion writers on Twitter so I know what Kate will be wearing when she next appears."
And she reckons Kate's down-to-earth attitude to fashion will help make her app a hit.
"Kate mixes high street with designer so you can find a lot of the things she wears in shops such as Reiss and Zara, which is where I buy most of my clothes."
