Whilst most of the stars got it right on the Oscars red carpet, the Vanity Fair after party was host to numerous fashion fails.

Kourtney Kardashian rocked up in a weird, shapeless black and red dress which was high necked and fell right to the ground, completely swamping her tiny frame.

Alessandra Ambrosio wore this weird, ill-fitting dress. Copyright [Rex]Victoria's Secret model Alessandra Ambrosio wasn't far behind in the worst dressed stakes.

She wore a gold and mesh coloured dress with embellishments and a weird collar which covered her entire neck.

Amanda Seyfried's dress wasn't on the money either. Copyright [Rex]Whilst Amanda Seyfried got it right on the Oscars red carpet in a cream gown, her after party dress wasn't in the same league.

This dress featured a thick red leather belt and complicated straps which were fastened around her neck.

Liberty Ross wore a very revealing top. Copyright [Rex]And then there was Liberty Ross, Kristen Stewart's nemesis who turned up in top which not only flashed way too much side boob, but was also completely see-through. Sometimes less is more.

Heidi Klum's dress was also very revealing. Copyright [WENN]Heidi Klum didn't get the less is more memo, either. Her dress was so plunging we don't know how she managed to avoid a wardrobe malfunction.

Then again, she IS a supermodel and she DOES have a figure to die for, so who can blame her for wanting to show it off.
