The 4-year-old royal arrived at Thomas’s Battersea in London, England, on Thursday morning, accompanied by her parents, Kate Middleton and Prince William, and her older brother, Prince George.
George and Charlotte wore their matching school uniforms, with Charlotte pulling her hair back into a ponytail. The princess found a way to stand out by attaching to her school bag a pink sequined unicorn key chain.
For the special occasion, Kate wore a beautiful, belted pink floral Michael Kors dress, and held her daughter's hand as they approached the school. Charlotte looked a bit shy, hiding behind her mom as cameras snapped photos.
Prince William was holding his 6-year-old son's hand as they greeted the teacher, Helen Haslem. Both George and Charlotte politely shook the teacher's hand as Charlotte nervously played with her ponytail.
"First day, she's very excited," William told the teacher of his only daughter.
Prince George has been attending Thomas’s Battersea for two years. In fact, his first day was a little more lonely as the news had just broken that his mother was pregnant with his brother, Prince Louis, and due to extreme morning sickness, she was unable to take her eldest to school.
Just like with the children of American presidents, it is tradition for the press to cover royal kids' first days of school and then agree to leave the kids alone afterward.
