Before we knew her as Catherine, Duchess of Cambridge, Kate Middleton was an art history student at St. Andrews, where she met Prince William. Of course, the rest is history. Young Kate Middleton loved to have a good time with her friends, always maintaining a carefree, effortless beauty look. As the saying goes, if it ain’t broke don’t fix it, and the duchess knows that minimal, natural beauty goes a long way.

Luckily, this worked well for her in her new role—royal rules enforce a strict code against cosmetics like colored nail polish. This is also why you’ll never see Kate with a bold red lip (though we’re sure it’d look great on her).

Still, the duchess is allowed to occasionally glam it up, sometimes with a more dramatic eye, but more often with her hair and epic hats. We took a look at her evolution from her days at St. Andrews to showing us a more glamorous side for the Royal Wedding, plus countless events around England.
