The Queen, who is known for her love of racing, looked resplendent in a pale blue dress coat and matching brimmed hat.

The headwear, with navy accents, co-ordinated with her handbag, gloves and shoes.

Beatrice and Eugenie, who have faced criticism in the past for their choice of hat, especially for those worn at Prince William's wedding to Kate Middleton, chose wisely this time opting for delicate headpieces.

Beatrice elected to wear a maroon cloche style — popular in the 1920s — which matched her lipstick and handbag, and flattered her red hair.

She wore a black and white jacket-style dress with studded belt which gaped open at the front revealing a black lining skirt underneath.

She accessorised with black heels and a simple gold necklace and bracelets.

Eugenie wore a creation by Sarah Cant, tilted to the side, which perfectly matched her off-the-shoulder knee-length mottled dress and nude stilettos.

The bodice of her frock clung to her curves before flaring out into a full skirt

Celebs also enjoyed their day at the races.

Elegant ... Samantha Barks

Les Miserables star Samantha Barks had a smile on her face as she wore a statement navy and polka dot hat with rosette.

She looked slender in a short white and blue body con dress.

Stylish ... Gemma Chan

Actress Gemma Chan wore a monochrome outfit with flourishing fascinator, while her comedian boyfriend Jack Whitehall opted for a grey checked three-piece suit.

Gemma was thrilled to be at the event as the "Official Face".

She took to Twitter to say: "On my way to Epsom for the Investec Derby. This year I'm honoured to have been asked to be the Official Face, good luck to all involved!"

Laura Whitmore looked glamorous in a cream and gold print minidress which showed off her slender legs.
