The royals were out in force on Saturday for the Investec Epsom Derby, with the whole family present to cheer on the Queen.
But all eyes were on the Duchess of Cambridge, who was certainly strides ahead of the rest of the competition in the sartorial stakes.
The brunette was super chic in a white chiffon Reiss dress paired with a white tweed Joseph jacket and nude LK Bennett courts.
The Chanel-style shape oozed relaxed elegance. And the short, floaty chiffon dress - which showed off her perfect pins - added a flirty touch to the ensemble.
To top off the regal look, the 29-year-old chose a Forties-inspired asymmetrical chignon that sat underneath a cappucino-hued fascinator.
She was accompanied by husband Prince William, who looked dapper in his top hat and tails.
Princess Beatrice was a close second, clad in a multicoloured floral shift dress with a matching oversized flower fascinator, further cementing her new-found sartorial clout.
