After multiple high street wears since getting engaged to Prince William, it comes as no surprise to us here at Catwalk Queen HQ, that The Duchess of Cambridge, formerly known as Kate Middleton, has the power to bring the high street to its knees when she decides to wear one of their dresses.


Following wears from Whistles and Warehouse, it was Topshop's turn to experience the madness when Kate stepped out with her hubbie and brother in law, at London's Harry Potter studios wearing their spotted jersey dress. Showcasing her slowly growing bump, Kate wore the casual dress with bare legs, all black accessories and her signature black blazer.

Frolicking around with her husband and his brother Prince Harry at the studios taking part in a mock wizarding dual (who says the Royals don't know how to have fun?), this was The Duchess' third appearance in the public eye this week. Since being snapped in her spotted dress, Topshop have sold out of the ultra affordable buy which was online for £38.


The Duchess also released an appeal video today for Children's Hospice Week, which runs from 26 April to 3 May, in which she also wore a Topshop number. Whilst Kate's wears might be well and truly sold out, you can shop Topshop's dresses here. Who knows what Kate will be wearing next week. Guesses anyone?
