This year's three-year-old princess wore a range of pretty, multi-colored dresses to many royal events this year.
The royal events she attended include the wedding of Prince Harry and Meghan Markle and her younger brother Louis Baptism.
But is there any reason why she always dresses or does she only find her more comfortable than pants?
Noble Ramberg, an award-winning Irish milliner, believes Charlott & # 39; s mother, the Duchess of Cambridge, is the cause of her dress sense.
Ms. Ramberg told Express.co.uk, "I do not think it's a royal tradition, I would say that it's a lot easier, why she's always in dresses."
"Maybe it's a lighter one , less analyzed wardrobe choice of her mother.
"If she wore pants and pullovers, the look would be more closely examined while a dress is timeless and simple."
What other wardrobe traditions follow the Royals?
Similar to Princess Charlotte, many other royals were photographed in public, repeating the same style of clothing.
Prince George is often seen in shorts, even in winter, which traditionally signals a child, belongs to the elite of the upper classes.
The four-year-old, who holds third place on the British throne, should be able to wear trousers at the age of eight.
However, George wore pants for his uncle Harry's wedding, where he acted as a page boy.
The prince's and princess's mother also dresses formally on public occasions, but is pictured wearing jeans in her downtime.
