It's a power suit showdown!
Kim Kardashian stepped out to dinner at Serafina in New York City last night dressed in an all-black getup underneath a tuxedo jacket with a neckline that was very, very low.
Kim's plunging V-neck top went almost down to her navel, giving her menswear-inspired outfit an extra dose of sex appeal. But Kim isn't the only one in the family to take the whole Diane Keaton-esque suit look and make it sexy.
Younger sister Kendall Jenner also stepped out in a plunging tux (sans bra) earlier this month. She showed up to her book signing with younger sister Kylie Jenner on June 3 in New York City wearing a sky blue tuxedo jacket, matching skinny pants and silver heels.
While Kim wore her black tux with voluminous, 1960s-inspired hair, Kendall Jenner went more modern and wore her hair pin-straight, parted starkly down the middle.
So which girl wore the better power suit: Kim or Kendall? Vote in the poll below!
