From Bjork to Cher, we round up the most daring looks in the Oscars history

On Sunday 28 February the world will see an array of stars descending on the red carpet of the 88th Academy Awards, where Hollywood is expected to appear in their best attire.

While the Hollywood glamour is something to be obsessed about, the world has also been obsessed with some looks that are just unforgettable - think of Bjork's swan dress at the 2001 Oscars (she was even dropping golden eggs on the red carpet). It was the inspiration for many stand-up comedies.

Cher made headlines in 1988, too, when she wore a beaded black outfit with a cape by Bob Mackie, matched with a two-foot headpiece, reportedly made of more than 800 rooster feathers.

In 1989, Demi Moore designed her very own outfit. It was a tapestry-lined gown and lace-edged cycling shorts. Kim Basinger got everyone confused in 1990 when she appeared on the red carpet in a scary full-skirted white gown with a single sleeve alongside ger brother - wait, was she marrying her brother? 

And Celine Dion risked it all in a backwards tuxedo from John Galliano for Christian Dior, matched with blingy Ray Bans and a Stephen Jones hat. 

What will be seeing on the red carpet this year?
