These days Fashion Week is a bit of a race. Who can Instagram a picture of the first look first. Who can be the first to get a selfie with Kendall Jenner. Who is the first to wear a collection straight off the catwalk.
As expected the red carpet turn-around has been incredibly fast this season. Emma Stone wore a red Altuzarra dress to the Vanity Fair Oscars party 8 days after it showed in New York Fashion Week. Taylor Swift wore a green Julien Macdonald gown 3 days after it hit the catwalk. Cara Delevingne wore a Vivienne Westwood black gown just two days after her LFW show. You get the idea.
But the fastest family of all are - you guessed it - the Kardashian-Jenners. Kim Kardashian wore a black ruffled Balmain AW15 dress to the front row - wearing it before it hit the runway. That evening her sister Kendall wore the same black ruffled dress to a dinner.
Take a look through the gallery above to see stars wearing looks fresh off the runway...
