Kate Middleton Looks Regal And Elegant In Christopher Kane Coatdress

It's Christopher Kane, no less.

The coatdress is back!

On Friday, Kate Middletonheaded to the Dundee Repertory Theatre with Prince William, donning her fave form of outerwear.

The royal blue topper, designed by Christopher Kane, looked chic and elegant on the 33-year-old Duchess of Cambridge, who paired it with black tights, and black Aquatalia boots. A black turtleneck worn underneath the coatdress added that extra touch of elegance to the ensemble.

Catherine also stuck to her signature beauty look: a touch of eyeshadow and liner, rosy cheeks and a soft pink lip. Her long brunette locks were left down, with a slight curl at the end, and her bangs swept to the side.

Kate was all smiles as she met with royal admirers waiting outside the theatre. Inside, she and William met with families who explained how they have been helped by mental health programs. The Duke and Duchess also met the cast and crew of the play "In Her Shadows."
