The whole world (including us) has been scrutinising Duchess Kate's Canada tour wardrobe from every possible angle, so it comes as little surprise to hear that she's prompted another instant sell-out.
The royal stepped off the plane on Prince Edward Island over the weekend wearing a chic cream shift dress from Joseph - and of course, the second it was identified, it started flying off the shelves, selling out in a matter of hours.
And even better for Kate style copycats? The Vanessa sleeveless crepe dress, originally £275, had just hit the summer sale - meaning it was retailing for a far more affordable £165.
It's hardly the first time the Duchess has prompted a high street buy to sell out - remember that Reiss Shola dress which crashed their website?
