The Duchess of Cambridge performed the royal tradition in 2012 while dressed in an emerald Emilia Wickstead coat, pictured above (at right). Her nod to the Irish holiday came in the form of a cheery sprig of shamrocks pinned to her coat. For 2014's parade, Middleton donned a Hobbs London coat accessorized with a Cartier shamrock brooch (above, center). And in 2015, Kate wore a brown Catherine Walker coat, a Lock & Company hat, and suede Emmy London pumps (above, left).
While she left the duty of attending the annual celebration to husband Prince William in 2016, last year she again stepped out in full green glory at the parade at Cavalry Barracks in Hounslow, London:
