We love that the sisters both rocked suits for the occasion, each putting their own spin on the tailoring trend with a few small styling tweaks.
Gigi added allure to her Derek Lam separates by wearing her double-breasted blazer sans top underneath. Sexy Christian Louboutin stilettos and a swipe of bold berry lipstick completed the look.
Going the sporty route, Bella walked the red carpet in chunky Chanel trainers and a white tee, which worked to relax her sleek Tom Ford suit.
Do you prefer Gigi or Bella's spin on the suit?
