Cheryl Cole has a Sienna Miller style moment on the X Factor

Cheryl Cole's X Factor wardrobe has been a veritable fashion fest of who wore it best moments - we had the Penelope Cruz Oscar dress, Emma Roberts' Costume Institute Gala frock, and then Beyonce tapped Mrs C's style for the MTV Awards - but the latest incarnation comes courtesy of Sienna Miller.

Following the sartorial furore that followed the Girls Aloud's controversial David Koma dress, she debuted a more demure take on styling for the Sunday's show, with a chic red Marios Schwab shift.

But she wasn't the first to snap up the elegant design. A full six months before, Ms Miller chose the scarlet stunner for a screening of flick, The Mysteries of Pittsburg.

And while both Brit beauties matched in the style stakes, they each gave the frock they're own signature spin.

For la Cole, this meant leaving those picture-perfect pins bare, slipping into nude leg-lengthening Brian Atwood platforms, and wearing that famous mane curly and loose.

Sienna, meanwhile, wore her hair high in a messy chignon, added black opaques and peep-toes and matched her dress to her pout, with a slick of ruby red lipstick.
