The Duchess of Cambridge looked ready to report for royal duty outfitted in a classic Catherine Walker skirt suit. Appearing polished and professional, the mom of three was seen in the company of some seriously regal sidekicks including Queen Letizia of Spain and Queen Maxima of the Netherlands. The royal squad also included the Duchess of Cornwall and Sophie Wessex.

And apparently the women shared a memo on how to dress for the day’s celebrations as they all selected white, cream or pale pink for their ensembles. Kate opted for a coatdress from Catherine Walker called the ‘Liza.’ The style features white wool crepe, matching buttons and a black piping detail in lace.

A similar style can be purchased from JcPenney.
