The sassy royal arrived at the christening of her baby brother Prince Louis sporting a completely new hair style. Charlotte wrote her brown hair parted in the middle, and accessorised with a blue headband featuring a bow which perfectly matched her dress and blue shoes.
The middle child of the Duke and Duchess of Cambridge is usually seen with her hair in a half-up style, or parted to the side.
The christening of 11-week-old Prince Louis marked the first time Prince William and Kate Middleton have stepped out with their children as a family of five.
Charlotte and older brother Prince George were on their best behaviour as they were greeted by Justin Welby, the Archbishop of Canterbury, who has now baptised all three of the royal kids.
