ASOS is currently getting festive with the Best Night Ever campaign, a chance to get yourself ready for party season with a little help from rapper Azealia Banks, singer Ellie Goulding and pink-haired model of the moment Charlotte Free.

The three rising stars have joined forces with the online fashion giants to produce three short video clips. But these are no ordinary videos - you can shop the looks worn by the stars directly from the ads. Just click the items you like, or watch the virtual shopping rail fill up as the video progressesm and pick your favourite ASOS looks.

The two musicians have lent more than their faces to the campaign; Azealia belts out new track Fierce whilst modelling half a dozen killer ASOS looks (and some amazing lippy) while Ellie dons sparkly hotpants, an embellished top and sky high wedges to perform the song Only You from her new album Halcyon.

ASOS fans can also get involved via Pinterest to win the clothes. Just pick your favourite look from Charlotte Free's gorgeous vid (below) and 'pin to win' by adding the hashtag #BestNightEver when you add the look to your board. You can also use the hashtag on twitter to chat to ASOS. Tweets are displayed on the ASOS site - fame at last!
