The Princess of Wales stunned in a £690 boater hat as she attended the installation of the first female Archbishop of Canterbury.
Arriving with her husband, Prince William, Catherine wore the accessory from Juliette Botterill, capturing eyes with the elegant style of the piece, which is crafted from black and ivory houndstooth straw.
The princess matched the hat with a Washington Prince of Wales cashmere coat from Suzannah, worth £2,850.
The number appears to be a bespoke version of the coat, which has natural fibres and sustainable attributes.

The princess completed her outfit in black stilettos while carrying a pair of black gloves and a bag.
The Prince and Princess of Wales's outing comes as part of Dame Sarah Mullally's installation as the 106th Archbishop of Canterbury.
The installation, traditionally referred to as an enthronement, represents the formal beginning of her public ministry as Archbishop.
Every previous holder of the position since St Augustine in 597 AD has been male, with women only permitted to become priests in the Church of England from 1994.

Upon their arrival at the cathedral in Kent, the royal couple were greeted by Lady Colgrain, the Lord Lieutenant, who introduced them to the Very Reverend Dr David Monteith, Dean of Canterbury.
William and Catherine walked through the Nave before taking their places in the Quire.
The couple is attending only as members of the congregation and has no formal role in the proceedings.
Approximately 2,000 guests are present for the service, including nurses and carers from Canterbury who were invited to honour Dame Sarah's extensive nursing career.

The Prince and Princess of Wales met with Dame Sarah last month at Lambeth Palace to discuss the work of the Church and the Royal Foundation.
Ahead of the event, a source close to the archbishop told The Sunday Times that she was "really delighted" that William and Catherine would be there for her installation.
The source explained: "The prince and the archbishop are both passionate about it [the Church] not being a private members' club and making it accessible and relevant.
"The improving relationship is wonderful and enables us to help defend and understand the prince's position.

"We would love the [future] supreme governor to be at church every Sunday, but one has to be practical around the fact that they are a couple with young children."
Dame Sarah's path to the highest office in the Church of England began with a nursing career that started in 1980.
By 1999, she had risen to become England's youngest ever chief nursing officer, a position she still held when she was ordained as a priest in 2002.
Her appointment as the first female Bishop of London came in 2018, paving the way for her elevation to archbishop.
