Who wore it best? Rachel Bilson vs Princess Eugenie

Rachel Bilson and Princess Eugenie played a game of style snap in Diane von Furstenberg. But who wore it best?

Rachel Bilson and Princess Eugenie put their style on trial when they both stepped out in the same rainbow-hued Diane von Furstenberg dress. But, who wore it best?

Perennial style setter Rachel Bilson was first to rock the frock, giving it its first public outing back in September last year.

The former OC starlet wore the DVF dress to take in some shows during New York Fashion Week, braving it bare-legged, and accessorising with lace-up ankle booties and poker-straight locks. 

Next up, and Princess Eugenie wore a slightly shorter version of the same zebra-print frock for a night out at Annabel's in London, only last month.

The Royal dressed for the chilly British weather by teaming her dress with black tights, towering heels and a purple clutch. 

Two stars, one uber-pretty frock. But, we want to know who YOU think wore it best... Leave your comments below!
