Red Carpet Roundup: Jennifer Lawrence stuns in Dior while Tracee Ellis Ross takes over with florals

With the 2018 Oscars just a few days away, Hollywood has been gearing up for its biggest night out.

A-list actresses and models put their best fashion foot forward this week, ready to take on the red carpet. One trend we're already seeing? Spring florals, as shown by Tracee Ellis Ross, Sofia Vergara and a very pregnant Miranda Kerr. 

Other favorites include Kate Upton's bright red pantsuit, Emmy Rossum's sophisticated royal blue outfit by Lela Rose and Oprah's intricate Versace gown.

The daring look was almost a wardrobe malfunction waiting to happen due to its deep cutouts -- but she totally rocked it. The actress has been slaying her sartorial show this week at her line of premieres for the new film.
