There are handful celebrities we
always look out for on the red carpet — and Olivia Wilde is one of them. You can pretty much count on her delivering a look every time she steps out of the house. From intricate braids to burgundy smoky eyes, she's never afraid to experiment — which is why her appointment as celebrity ambassador of Revlon makes perfect sense.
But it wasn't until we took a trip down memory lane that we realized just how much of a beauty chameleon Wilde is. She rarely repeats a look, and she's on top of every single trend (if she's not kicking it off).
Monochromatic makeup? Wilde has been experimenting with it since 2005. Winged-out smoky eyes? She's a master. In honor of the actress' birthday tomorrow, we decided to round up 25 of our favorite looks, ahead.

The OC, Wilde had honey-blond hair fit for a pop star. Photo: Lawrence Lucier/FilmMagic. More
Once 2005 hit, she began her transition to the brunette color we know and love. But that's not all: If you look closely, you can even see the beginnings of Wilde's love affair with
monochromatic makeup. The warm, tangerine shades on her eyes complement her bright-orange dress perfectly. Photo: Jon Kopaloff/FilmMagic. More
In 2005, Wilde experimented with face-framing fringe at

Rush, Wilde opted for another '60s-style look complete with a mod cat-eye and peach lips. Photo: Alberto E. Rodriguez/Getty Images. More
It's hard to pick which we love more: Wilde's smoky eye, or her voluminous, ombré hair from the 2014 Golden Globes.

This diffused graphic eye from 2015's Met Gala is one of our favorite looks. And, of course, we're always down for a hair accessory.
