“Typically the ‘Duchess Slant’ is used when a lady has to sit for an extended amount of time while keeping poise and posture,” Myka Meier, royal etiquette expert and founder and director of Beaumont Etiquette, previously told PEOPLE.
Kate (and now Meghan Markle!) have been regularly photographed using the “Duchess Slant.”
In the sweet shot, taken by photographer Alex Bramall, George and Charlotte join their fellow bridal party members, cousins cousins: 4-year-old Mia Tindall; Savannah, 7, and Isla Phillips, 6; and 5-year old Maud Windsor (who attends Thomas’s Battersea with Prince George).
Also among the bridesmaids is Theodora Williams, 6, the daughter of British singer Robbie Williams and his wife Ayda Field. And among the page boys is Louis De Givenchy, 6 — the son of Zoe and Olivier De Givenchy.
The little bridal party members wore designs by Amaia, one of Princess Kate’s favorite children’s wear designers.
