See Kate Middleton's blue Easter dress in photos

The royal family celebrated Easter Sunday today with a religious service at St. George's Chapel, at Windsor Castle. Kate Middleton was on hand for Easter. She was delightful when she arrived at the chapel with Prince William.

For today 's service, Kate wore a pale blue tunic with a gray hat and a small clutch. Earrings, a brooch and gray heels complete the look. See the complete set of the Duchess of Cambridge here:

Will and Kate have become regulars of Queen's East service. Members of the royal family have been there for the last two years and even joined the traditional celebration last year, just weeks before welcoming Prince Louis. In 2017, the Duchess of Cambridge wore a cream dress and a matching hat for the occasion. Last year, she chose a brown coat with a matching hat:

This year, Easter is also another special day for the royal family: the 93rd birthday of Queen Elizabeth. While the monarch usually marks the day privately, this year we had a glimpse of the celebration while the royal family was going to the church. After the service, the Queen and other Royal ladies received bouquets of local children's flowers. In June, the monarch will officially celebrate her birthday with Trooping the Color, her annual parade in London.

Many other members of the royal family have been spotted serving today, including Prince Andrew, Princess Beatrice and Princess Anne. Anne's children were also present with their respective wives – Peter Phillips brought his wife Autumn, while Zara and Mike Tindall were also seen serving. Prince Edward and his family were also present.

Prince Philip was not present for the second year in a row. Prince Charles and Camilla missed the service – they traditionally spend Easter in Scotland – and the Duchess of Sussex was not present either, as she looks forward to the arrival of their first baby.
