On Saturday night on the X Factor it was Rock week.

I half expected Cheryl Cole to come out wearing a rock chick-inspired Balmain look, but she surprised everyone by wearing a black David Koma Fall 2009 mini dress with Tabitha Simmons Carla suede thigh-high boots.

Her halter neck keyhole dress had an interesting bodice detail of silver tone tubes.

The dress was an interest bold choice, and totally different from what we have seen on the Atelier Versace loving X Factor judge.

I wasn’t crazy about the look, but I didn’t hate it.

I would’ve dislike her look if her hair wasn’t pulled back. The bouffant wouldn’t have worked with this look.

Georgian born designer David Koma graduated in 2009 with distinction in MA Fashion from Central Saint Martins.

David’s pieces are sold exclusively online at Browns Fashion.

After Saturday’s show the press heavily criticized Cheryl’s David Koma dress, saying it looked like a pair of alloy wheels or dustbin lids.

This criticism may have been the reason why Cheryl toned down her look on Sunday night.

She still managed sparkle with her gorgeous smile and gold sequined Les Chiffoniers pants, which she wore with an asymmetrical black slashed top.

Slashed tops was one of the major trends of Spring 2010 fashion week.

She accessorized with a gold peep-toes, a selection of bracelets and a poppy.
