X Factor's Kelly Rowland in Christopher Kane

It's no secret Kelly Rowland has been a fashion force to be reckoned with, especially as of late. Whether she is rocking a stick straight style or a sassy bob, Kelly is a style chameleon.

Last night's X Factor style was no exception. Looking flawless head to to and accenting her gorgeous figure, Kelly shined in a modified Christopher Kane dress from his Spring 2013 collection and Gianvito Rossi heels.

Kelly posted this coquettish pic on Instagram last night before the show. What do you think of her look?
