“As she’s grown into her role, she has become more confident and is not afraid to make some bold choices.

“We’ve seen her swapping her skinny trousers for high waist, wide leg styles and she makes an effort to reflect current trends in subtle ways with fabric, colour and pattern choices.”

While royal women are typically seen sporting traditional high heeled closed toe pumps, Kate has been “a little more adventurous with her shoes”, partial to a block heel, wedge or sandal.

Most recently, on her royal Caribbean tour, Kate made headlines when she wore her £350 Stella McCartney Hestia Espadrille shoes with a gold anklet attached.

Melissa remarked: “Kate wore a blush Alexander McQueen to Pippa’s wedding and Pippa wore a similar dress style by Alexandra Rich to Prince Louis’ christening.”
