For her first two trips down the aisle, Angelina Jolie kept it casual. Extremely casual.

At her first wedding to Jonny Lee Miller in 1996, the actress -- who turns 37 Monday -- opted for a pair of rubber pants and a T-shirt with her love's name reportedly written across her back in blood. When she tied the knot with Billy Bob Thornton in 2000, Jolie wore a tank top and jeans.

Twelve years later, the A-lister consistently tops Best Dressed lists, rocking designs from couture houses like Versace and Giorgio Armani on the red carpet.

We're confident when it comes time for her to walk down the aisle with her love of seven years, Brad Pitt, Jolie will opt for something equally high-fashion -- but also uniquely her.
