She accessoried with a pair of brown leather gloves, which she held in her hands.
The former actress also wore a pair of small diamond drop earrings in her ears.
Meghan kept her makeup simple for the day, sticking to light eyeshadow and bronzer, and a nude lipgloss.
She wore her hair down in a straight style, choosing something simpler than her usual bouncy curled look.
As well as Harry, Meghan was joined by the Duke and Duchess of Cambridge, and the four walked along next to each other, led by Prince Philip.
Princess Beatrice could also be seen walking behind them, alongside other members of the Royal Family.
After church, the royals will return to Sandringham for Christmas Dinner with the Queen.
As with everything in royal life, the festive season follows a particular rhythm, and the day will go to strict timings.
The Queen’s former personal chef Darren McGrady has revealed exactly what the family enjoy.
Speaking to GoodHousekeeping.com, he said: “After church, that’s when they have a big lunch that includes a salad with shrimp or lobster, and a roasted turkey, and all of your traditional side dishes like parsnips, carrots, Brussels sprouts and Christmas pudding with brandy butter for dessert. They stick with the same meal year after year.”
