Princess Catherine looked to be in good spirits as she joined her family for Sunday service this past weekend.

She and husband Prince William were photographed driving to Crathie Kirk, a church on the royal family’s Balmoral estate in Scotland, to join King Charles III and Queen Camilla for the service. Other family members, including Prince Edward and Duchess Sophie, and Princess Anne’s husband, Tim Lawrence, also attended. (See the photos here.)

For the day, Kate wore an elegant look with a boho spin. It was composed of long brown tartan trench coat from Holland Cooper, plus a brown felt hat adorned with several feathers, from Hicks & Brown. She also accessorized with dangly gold earrings.

Prince William looked sharp in a blue suit and crisp white shirt, while Charles and Camilla opted for colorful Scottish tartan ensembles.

Kate’s unexpected appearance at the family event marks the first time we’ve seen her since she made a surprise appearance at Wimbledon in July. Then, the princess looked exquisite in a royal purple dress next to daughter Princess Charlotte and sister Pippa Middleton.

Prior to the tennis match, Kate’s last public appearance was at Trooping the Colour in June. Then, she looked radiant in a white long-sleeved midi dress with black trim by Jenny Packham.

The Princess of Wales has been lying low as she continues to undergo treatment for cancer. She revealed the news of her diagnosis in a candid video message in March, and explained that she is being treated with preventative chemotherapy and “getting stronger every day.”
