Now that Winona Ryder is on the road to career comeback, the 1990's blockbuster babe should think about hiring a stylist!

Upping the style ante at the swanky screening was Mila Kunis, who showed off her bombshell body in a rosy Elie Saab gown, and Natalie Portman in an off-the-shoulder Christian Dior gown.

Reese Witherspoon got dressed in sophisticated style to receive her star on the Hollywood Walk of Fame.  The blonde beauty opted for a Dolce & Gabbana polka dot frock, which she perfectly paired with red heels.
