The fashionable young sisters arrived at Westminster Abbey Tuesday morning with uncle Prince Edward and his wife Sophie, the Countess of Wessex, dressed to impress as they prepared to celebrate the 60th anniversary of the Queen's coronation.
Beatrice, 24, and Eugenie, 23, are known for their unique flair when it comes to clothes (and their obsession with fabulous hats), and the pair did not fail to disappoint on this occasion.
Beatrice chose a Victorian-style high-necked coat by Hannah Coffin, with oodles of beading and an a Sarah Cant feathered hat. Taking a style note from The Duchess, she finished the look with L.K. Bennett shoes.
Eugenie, on the other hand, surprised us by donning a teal biker-style jacket over her Burberry dress. She too (of course) finished the look with a deep purple cocktail hat by Robyn Coles and, just like big sis, a pair of L.K. Bennetts.
