Oscars 2016: Who wore it best? Reese Witherspoon and Tina Fey twin in purple gowns

Fashion fans did a double take as they spotted Reese Witherspoon on the Oscars 2016 red carpet in a deep purple gown.

Just minutes earlier, they'd seen Tina Fey swish by in a remarkably similar dress.

In almost exactly the same hue, both gowns were strapless, cinched in at the waist and had fishtail detail.

Tina paired hers with a statement, bejewelled necklace and a sleek updo, while Reese topped her look off with silver diamond cuffs and slicked-back hair.
