We've Found the Chicest Way to End the Week

Another week has passed, and it couldn't have been a more stylish one. That's because Marion Cotillard wrapped things up with another stunning Dior design. Joined by Nina Dobrev in a bold, printed mini and Megan Fox who wore Oscar de la Renta, it's safe to say this may have been one of Summer's most stylish weeks.

And they weren't the only ones who dressed to impress — streamlined designs from Julianne Hough, Megan Fox, and Maggie Gyllenhaal stole the show this week. As soon as they hit the red carpet, we knew that if these looks were any indication, we were bound for a stylish seven days. Scroll down to get this fashion party started!
