Katherine Heigl vs Selena Gomez: Who wore it best?

These two celebs both look great in this Reem Acra dress, but who wore it best?
Katherine (Left) wore a blue version of the dress to the premiere of the film The Ugly Truth in New York.
She teamed it with black peep toe heels, silver jewellery and slick hair.
Selena (Right) wore a slightly shorter, purple version of the dress to the premiere of Boyfriend Justin Beiber's new film Never Say Never.
She wore it with a pair of nude heels, a cute metallic clutch bag and curled hair.
I think selenas look seems slightly more classy for the red carpet, but what do you think?
