Kate Middleton once again showed off her prudent side yesterday as she attended a royal engagement with her husband HRH Prince William in a a high street frock. The Hobbs wessex dress was in the sale for £35 but promptly sold out as images of the Duchess of Cambridge appeared online. She teamed it with a woven belt and her signature wedge sandals. Unfortunately her actual dress has sold out, but you can shop similar styles below including this dress by Vivienne Westwood (£200) which we love. Do you like this look on Kate?
