The 33-year-old royal sported the hairstyle when she and Prince William headed to Crathie Kirk church in Scotland for morning prayers on Sunday, September 13, reported Ace Showbiz.
Kate, who hadn't been spotted in public in two months since her appearance at the America's Cup, looked chic in a black turtleneck and a brown Hobbs coat as she sat on the passenger seat of a Range Rover driven by William. She completed her look with small gold earrings.
The royal couple drove from Balmoral Castle to the church in a convoy of cars.
Kate is expected to return to royal duties this week, which include a visit to a school in London run by the Anna Freud Centre and attending the opening ceremony and first match of the Royal World Cup on Friday with Prince William and Prince Harry.
