Kim Kardashian donned a dramatically different ensemble to an event for self-help author-turned-Congressional candidate Marianne Williamson last night in Los Angeles.
The E! reality star wore a pair of black silk harem pants with a black tank and blazer.
Kourtney Kardashian joined in on the fun and opted to wear a decidedly more feminine outfit for the evening outing.
The mother of two was very on trend as she mixed prints by wearing a striped blouse, floral knee-length skirt, and a pair of floral pumps. Cute!
But the Hollywood star power didn't end there…
Katy Perry was also on hand to support Williamson and her close gal-pals.
The "Dark Horse" singer showed off her newly-dyed green hair and looked adorable in a floral cut-out dress.
Perry evoked '90s grunge glam by pairing the frock with a pair of clunky black platforms.
Nicole Richie also showed off her colorful coif as she mingled with politicians and pals.
Dressed every bit the part of the fashionista, Richie wore a white monochromatic getup comprised of a turtleneck, blazer and pair of trousers.
The star of the upcoming VH1 show Candidly Nicole tweeted out her support and a video endorsement for Williamson.
"I support Marianne Williams because I think that America is ready for positivity, strength and enlightenment," she says in the clip.
Williamson is currently running for California's 33rd district after Rep. Henry Waxman retired last year.
