Just try to keep up with the Kardashians, we dare you.

Kourtney and Kim have been on an insane promotional blitz, hitting every major talk show in New York to promote their new reality show, Kourtney & Kim Take New York, premiering this Sunday at 10 p.m..

Of course, every appearance requires a new outfit, natch, and the ladies came prepared with a helluva lot of couture.

Kim stuck to kurve-hugging dresses and stilettos for her appearances on Today, Live With Regis & Kelly, The Seven and The Wendy Williams Show (from left to right), with cazh jeans thrown in for the Knicks-Jazz game.

Mason's mama paired blouses with skirts and pant suits, and mixed in a frilly dress for good measure. Her striped dress at Wendy Williams (center) was a fail, but Kourt redeemed herself in a fierce zebra-print sweater at the airport.

So which getup do you like best on each sister? And whose look do you prefer, Kim's simple 'n' sexy style or Kourtney's varied outfits? Weigh in below!
