Princess Charlotte is the second eldest of the Cambridge children. Her full title is Princess Charlotte of Cambridge.
While her royal title was bestowed upon her at birth, it is likely to change to something new when she becomes older as her role within the royal family shifts.
So what will her future title be? She is fourth in line to the throne after her grandfather Prince Charles, 69, father Prince William, and her elder brother Prince George, 5.
Given there are three people before her in the order of succession, it is unlikely Princess Charlotte will ever be Queen.
However, there are still other titles Princess Charlotte may be able to gain during her life.
Princess Anne, 69, the Queen’s sister, gained the title of Princess Royal in 1987. Only one person can hold this title at once.
The Queen’s aunt, Princess Mary, previously held the title, before she passed away in 1965.
It is also possible Princess Charlotte may gain a royal dukedom if and when she one day marries.
Prince William, for instance, was granted the title of Duke of Cambridge upon his marriage to Kate Middleton, 36.
Whatever her title changes to, it is likely she will remain known as Princess Charlotte by the public who have become used to the name.
Charlotte may one day hold multiple titles at once, as many other royals have been known to do.
For instance, Prince Harry still holds his Prince title after gaining a dukedom upon his wedding day to Meghan Markle, 37.
He is now known as Prince Harry, Duke of Sussex, rather than Prince Henry of Wales, as he was known from birth.
As a key member of the royal family, Charlotte is still subject to royal protocol despite her young age.
Princess Charlotte is unfailingly pictured in dresses, but never trousers. Now an expert has revealed why.
It is to guarantee she never looks “out of date”, said childrenswear designer Rachel Riley.
Rachel has previously dressed Prince George, Charlotte’s older brother and third-in-line to the British throne.
“If [the royal children] wear very simple things… it’s timeless in that you can’t really date a specific photo or put them in something that seems out of date,” she told The Telegraph.
“They have chosen a very traditional look and are a traditional family.”
She added that the Cambridge’s favour a “timeless” look over attention-drawing clothes for their children.
“The reason why I design clothes that way is because if they wear very simple things, it’s about the child, and it’s timeless in that you can’t really date a specific photo or put them in something that seems out of date.
