Princess Eugenie has shared the most adorable wedding-themed throwback photo

OK, this is too cute.

Princess Eugenie has shared the most adorable wedding-themed throwback photo. The 28-year-old took to Instagram on Thursday to share a side-by-side photo of her when she was younger and on her wedding day last October. The first photo shows Eugenie as a little girl, wearing a wedding a white dress, floral headband and veil. She can be seen grinning at the camera as she holds a bouquet of white flowers. The second photo shows Eugenie beaming as she walked into St. George's Chapel on her wedding day last year. While her floral headband was swapped out for a sparkling tiara (Greville Emerald Kokoshnik Tiara, borrowed from Queen Elizabeth, to be exact), there's definitely an adorable resemblance between the two photos. "Same same but different," she wrote alongside the side-by-side shot, adding #tbt. Princess Eugenie and Jack Brooksbank said 'I do' in front of 850 guests,  as well as 1,200 members of the public who were waiting outside St. George's Chapel, in October last year. Their wedding day outfits are currently on display in an exhibit at Windsor Castle, much like Prince Harry and Meghan Markle's were last year. As part of the exhibit, Eugenie spoke about the decision to have a low-cut back on her gown - which showed off a scar on her back stemming from scoliosis surgery. She said [via the Daily Mail]:

“I had always wanted a low back – part of it was showing my scar and I believe scars tell a story about your past and your future, and it’s a way of getting rid of a taboo. “For me, it’s a way of communicating with people who are going through either similar situations with scoliosis or having a scar of their own that they are trying to deal with.” “We started getting a lot of letters from people who were happy that I had stood up and showed my scar, and people with scoliosis, letters from girls that are going through the same thing and I definitely was very touched by everyone’s support.”
