Last Friday, Oct. 12, was one of the most memorable days for royal fans. We got to watch Princess Eugenie walk down the aisle at St. George’s Chapel and marry her now-husband, Jack Brooksbank, surrounded by her closest family and friends. And on Tuesday, Oct, 16, just a few days after saying “I do,” Eugenie shared a thank you message to everyone on Instagram with a cute photo — but of course, it was little Princess Charlotte who stole the spotlight in the pic!

“Jack and I would like to thank everyone who was involved in making our day so special and for all the wonderful wishes as we start married life laughing together,” Eugenie, 28, captioned a snap of herself, Jack, and all their bridesmaids and page boys from their special day (the photo was taken by their family photographer Alex Bramall). And while it was absolutely adorable to see all the young ones smiling and laughing with the bride and groom, Charlotte’s perfect smile is one we’ll seriously never forget!

Kate Middleton and Prince William’s three-year-old daughter — in her cute white dress and a half up, half down ‘do — looked happy as ever to be posing alongside her second cousin on her special day. Her candid laugh? It actually made our day. Better yet our week.

But don’t worry, that’s not the only cute thing Charlotte did at the nuptials. In the other set of portraits shared by Kensington Palace, the young royal was spotted doing the “Duchess slant.” The toddler followed suit of her mother and Aunt Meghan Markle by adopting the style of sitting. The “Duchess slant” is when a woman’s knees and ankles are kept tightly together and her legs are slanted to the side, and it was allegedly named after the Duchess of Cambridge.

“Typically the ‘Duchess slant’ is used when a lady has to sit for an extended amount of time while keeping poise and posture. It is the perfect pose for when a camera is shooting directly in front of you because by slightly slanting the knees to create a zig-zag effect when wearing a dress or skirt, your legs are angled so that the camera only shoots the sides of your legs and protects your modesty,” Myka Meier, a royal etiquette expert and the founder and director of Beaumont Etiquette, told People. Charlotte is already fit to be a Queen!
