Unlike her husband Prince William, who was born into royalty, Kate Middleton was not always one of the planet's most recognizable human beings.
It's hard to imagine now, since she has become not just globally famous, but a style icon of modern times, but Kate grew up a very regular young woman.
Growing up in England, Middleton was always a natural beauty, albeit a little less polished than the refined 32-year-old who we are familiar with today.
We mean that as a compliment, as the People's Princess retains a down-to-earth charm that's made her infinitely relatable and immensely popular.
