Kate Middleton hasn't always been royalty. Long before she was the Duchess of Cambridge, Middleton was walking down the aisle along with her younger sister as a junior bridesmaid in 1991. At just 9-years-old, Middleton participated in her Uncle Gary Goldsmith's wedding to Maranda Foote along with her 7-year-old sister, Pippa. The siblings wore matching pale pink bridesmaids dresses and flower crowns during the ceremony.
