Kate chose the Australian label’s cream lace Roamer Day Dress – which retails for $495 – from its upcoming Summer Swim 2014 collection, pairing the frock with a pair of sky-high tan wedges.
The designer dress, which was also worn by Naomi Watts for a recent ad campaign, went on sale today.
Kate has a proven ability to sell fashion – with copycats around the world buying her stylish outfits within minutes of seeing them on the Duchess.
The Diane Von Furstenberg wrap dress she wore to the Blue Mountains sold out worldwide in just eight minutes and within seconds of the Duchess stepping out in the Zimmermann dress in April, the label’s website had crashed.
Today is likely to be no different, with the brand likely to see a massive increase in sales thanks to the royal seal of approval.
