The Duchess of Cambridge looked beautiful in blue as she arrived to Royal Ascot on Tuesday.

Kate Middleton donned a light blue Elie Saab dress detailed with lace and a pussy bow for the first day of the horse racing event.

The duchess accessorized her outfit with a matching hat, silver clutch and silver heels. Her hair was swept into a braided side chignon.

The duchess did not attend Royal Ascot last year after she just gave birth to Prince Louis in April.

Royal Ascot is one of the most anticipated social events in the United Kingdom. It is attended by the queen and other members of the royal family.

In addition to exciting horse races, the event features some serious fashion from attendees.

Like Middleton, Queen Elizabeth, Princess Beatrice and Princess Eugenie also wore a shades of blue this year.
