Princess Charlotte's £89 shoes share the same name as Princess Beatrice's daughter, Sienna.
The 10-year-old princess joined her father, Prince William, at the Women's Euros final in Basel, Switzerland, over the weekend.
Charlotte paired her £70 Guess dress with white buckle shoes from Papouelli, the same footwear worn by the princess at King Charles's Coronation in 2023.
The "Siena" shoes retail for £89, but unfortunately for royal fans, they are currently sold out in all sizes.

Sienna is also the name of Princess Beatrice's eldest child, whom she shares with Edoardo Mapelli Mozzi.
The three-year-old was christened Sienna Elizabeth Mapelli Mozzi; her middle name was a nod to the late Queen Elizabeth II.
Beatrice and Edoardo welcomed their second child in January 2025, another daughter named Athena Elizabeth Rose.
Edoardo, 41, also has an older son named Christopher Woolf (Wolfie) with his ex-partner, Dara Huang.

Charlotte's shoes have the following description: "The Siena strap shoe has a narrow buckle over the foot.
"Extremely soft leather and soles make this shoe very suitable for special occasions, like weddings, first communions and parties.
"In metallic silver as well as white and cream leather. Please note this shoe runs a little narrow."
Princess Charlotte attended the final of the Women's Euros wearing a £70 chiffon midi dress from Guess.

The garment featured a "crew neck with short sleeves", according to its description.
The 10-year-old previously wore the dress to watch the Wimbledon Men's Singles Final in 2024 alongside Princess Kate and Pippa Middleton.
Following the Lionesses' victory, Prince William and Princess Charlotte shared a congratulatory statement on social media.
They wrote: "What a game! @Lionesses, you are the champions of Europe and we couldn’t be prouder of the whole team. Enjoy this moment @England. W & Charlotte".
