Today marks Princess Eugenie's 33rd birthday, and her mom is celebrating the occasion in the best way: with a rare throwback pic.
Sarah Ferguson, 63, shared an Instagram snap of the princess as a little girl—and her stylish outfit is taking us straight back to the '90s. In the caption, the duchess wrote, "Happy Happiest of birthdays, my Eugenie. Spring flowers always tells me the excitement of your birthday is soon and here we are. You are my magical beloved daughter and I am so proud of you."
