Princess Eugenie may have just hinted at her royal wedding theme with the throwback photo she uploaded on Instagram.

The 28-year-old royal posted a picture of herself as a young girl enjoying a bite of her cotton candy. In the snap, Princess Eugenie is wearing a plaid sweater, blue long-sleeved top and necktie, and khaki pants. The daughter of Prince Andrew and Sarah Ferguson captioned the photo, “#tbt to really cool moments in life.”

Chloe Best, a journalist for Hello!, said that Princess Eugenie may have just hinted on her wedding theme. Best said that cotton candy may be featured at the princess’ royal wedding to Brooksbank on Oct. 12. After all, Princess Eugenie reportedly planned a fun fair vibe for her wedding reception.

Last week, Princess Eugenie also treated her thousands of social media followers with another throwback photo. But this time around, she was joined by Ferguson and Princess Beatrice. The picture of the trio was taken during the siblings’ first day of school in 1994. They were seen in their matching uniforms.

“Throwback to school days. Clearly, I was more excited than Beatrice!” she captioned the picture.

In related news, Princess Eugenie has revealed the dress code for her wedding. She and Jack Brooksbank have requested their female guests to wear day dresses and for their male guests to wear morning coats. The attire for the male guests is quite different from what Prince Harry and Markle asked from their friends and family.

Since Markle is American, some of her male friends are not used to wearing morning coats. As such, they were allowed to wear lounge suits. Prince Harry and Markle also gave their guests more information regarding the proper dress code days before the wedding. The same can be expected from Princess Eugenie and Brooksbank.

The royal couple will tie the knot at St. George’s Chapel in Windsor Castle. A reception will follow at St. George’s Hall and the Royal Lodge.
