WireImage/Getty Images/Brandon HickmanWe can't believe it either—Giuliana Rancic is ringing in 40 today! The E! star looks better than ever, and her impeccable style is just as ageless as the rest of her. The E! News host has made her way down many a red carpet, and we'd venture to say she's mastered the art of being best dressed.
The first look that comes to mind? The ethereal Paolo Sebastian Couture gown that Giuliana wore to the 2014 Oscars. But really, it was her exquisite Roberto Cavalli red gown from the 2011 Emmys that may be her biggest fashion win yet.
Even in a simple white gown at the 2011 SAG Awards, G crushed the red carpet. The Fashion Police co-host called on her superb sartorial senses again for the 2012 SAG Awards, and certainly didn't disappoint in an illusion-paneled Basil Soda red dress.
Rounding out her top fashion moments is the Tony Ward confection she wore to the 2012 Academy Awards. One word: amazeballs.
No matter the age, one thing's certain: Giuliana will always be a best-dressed list regular. So happy birthday, Giuliana, and keep up the impressive style work!
