Following the passing of Queen Elizabeth II on Thursday, Kate Middleton will likely take the same title as Princess Diana: Princess of Wales.

QUEEN ELIZABETH II REMEMBERED AS KING CHARLES III ASCENDS THE BRITISH THRONE

Middleton, the Duchess of Cambridge, is likely to take on the title as the queen's eldest son, Charles, now is known as King Charles III, ruler of the British throne.

When Charles became king, his former title of Prince of Wales became available. Charles' eldest son, Prince William, and now official heir to the throne, will be offered his father's former title.

Ultimately, this would make Kate the Princess of Wales. This special title was last used by Charles' then-wife, Princess Diana, who died in 1997 at age 36.

And it's not just a royal title that marks a similarity between Diana and Kate. On numerous occasions, Kate has also dressed like Diana, recreating some of her most iconic looks.

In June 2022, at the Royal Ascot, Kate wore a brown and white polka dot dress by Alessandra Rich and paired it with a hat featured floral details on top by Sally-Ann Provan.

Back in 1986, Princess Diana also wore a polka dot outfit to a different horse racing event: the Epsom Derby. Diana wore a white dress by Victor Edelstein along with a similarly dotted hat by Frederick Fox for the occasion.

While passing on the title does not automatically happen, it still usually occurs when the existing Prince of Wales ascends the throne, as Charles did Thursday.
