After being spotted at the Ralph & Russo store [1] one day before her sister's wedding, Princess Beatrice did, indeed, step out in the designer on Eugenie's special day [2]. Our suspicions were clearly right on the money, but we didn't expect Beatrice to look this downright stunning in her indigo ensemble — did anyone catch that unexpected bee brooch [3] or the silver leaf top handle of her bag?

Beatrice's pale blue accessories were also designed by Ralph & Russo, and they made a fine contrast to her sophisticated top and skirt. She looked lovely as she accompanied her mother, Sarah Ferguson [4], into the ceremony, where she gave a heartfelt speech [5]. Who knew teal and indigo would look so hip and cool standing next to each other? Read on for a peek.
