It's no small feat to steal the spotlight on the Academy Awards red carpet, where high-impact glamour is par for the course. But in a sea of impossibly gorgeous gowns, these five actresses did just that. Now the competition in this best dressed pool is even stiffer: First, Lupita Nyong'o took our breath away in a pearl-embellished custom Calvin Klein Collection gown. Then, Emma Stone stunned in Elie Saab sparkle. Next up, Naomi Watts wowed in a sexy, side-cutout Armani creation, Rosamund Pike brought the heat in a fiery custom Givenchy strapless, and Julianne Moore's custom Chanel left us totally in awe. Now it's time to make the call: who deserves that best dressed title?
