Guests of honor! Kate Middleton and Prince William were wedding-ready on Saturday, when they attended the nuptials of Pippa Middleton and James Matthews at St. Mark’s Church on the Englefield Estate in the English county of Berkshire.

Keeping the attention on the bride and groom, the royal family arrived at the service far away from the crowds and press. Kate was briefly spotted with her children inside the doors of the church. She also was seen smoothing out the train of her sister’s dress before she walked down the aisle.

Serving as a page boy and a bridesmaid, respectively, for Aunt Pippa’s big day, the two tiny royals looked adorable in their matching outfits.
