Kim and Kourtney Kardashian Are #Twinning in '50s Fashion #TBT

Before they took New York Fashion Week by cleavage-baring, fur-lined, paparazzi-crazed storm, the Kardashians were just girls trying to find their sartorial footing in matching outfits styled by Mom.

For Kim and Kourtney, that meant retro poodle skirts, sweaters cross-stitched with "K" and high ponytails adorned with bows.

"#TBT... matching, of course!! @kimkardashian @kourtneykardash #mygirls #love #family #proudmama," Kris Jenner captioned a vintage Instagram of her older daughters in all their '50s glory.
