Kate Middleton just wore the most stylish Rixo dress to do the morning school run

The Duchess of Cambridge looked so chic.

The Duke and Duchess of Cambridge were spotted doing the school run on Wednesday, and all we can say is wow.

While Prince George, Princess Charlotte and Prince Louis don't officially start their new school until Thursday, the family headed to Lambrook a day early for a settling-in session.

All three children looked as smart as ever in their summer uniforms, however it was Kate's dress that stole the show.

The Duchess opted for a brown polka dot shirt dress for the occasion, from one of our favourite fashion brands, Rixo.

The 'Izzy' dress features a white polka dot print, with puffed sleeves, a relaxed collar and a pleated skirt. It's no surprise that the dress sold out in no time (that's 'the Kate effect' for you), however the website says that more stock is coming soon, hurrah!

Izzy Pleated Shirt Dress, £245 | Rixo
Rixo's 'Izzy' dress has all the effortless prep of a Hepburn-esque shirt dress, made unique by the vintage-inspired Copper Dot print.
