Everyone knows that slipping into a Roland Mouret dress equals an instantly amazing figure, and it's certainly worked for these two famous ladies. Katy Perry and Kanye West's girlfriend Amber Rose both fell for this RM by Roland Mouret Mona dress and wore it out on the very same day. Amber was spotted first, hitting the shops on Rodeo Drive in hers, and teaming it with shades, sandals and half an arm of chunky gold bangles. Katy went for a more dressed-up effect, slipping on black stilettos and arming herself with a giant clutch as she arrived at the Chateau Marmont in LA. We think both ladies take pretty in pink to a whole new level, but there can only be one winner. Vote away, fashion fans.
