If we talked back in 2003, I would have assured you that no celebrity on the planet was, nor ever would be, capable of getting between me and my collective girl-crush on Mary-Kate and Ashley Olsen.

But that was before Kate Middleton scored the sapphire engagement ring. And before Kate Middleton had that wedding. And before Kate Middleton took to enjoying long walks in pastoral fields wearing perfectly oversized sweaters and wellies.

Next best thing to being Kate? Dressing like her, obviously. Proving to the world that bold brights are best, that sacrificing shape is silly, and that, no, nude shoes do not make a girl look barefoot, she’s become a fashion icon in her own right – with less than two years as Duchess behind her. And now, using our Make It Your Own: The Duchess’ Style Boutique (consider it a birthday tribute; she’s 31 today) – Kate’s look can be yours.

Our Make It Your Own: The Duchess’ Style Boutique opens Wednesday, January 9, at 11AM ET.
