For some reason, the press feel the need to constantly compare the dresses worn by X Factor judges, mentors and apparent rivals, Tulisa Contostavlos and Nicole Scherzinger. We're not sure that either one is particularly coming out on top in the style stakes, but we do know that Tulisa's all sparkles dress from last night's Live X Factor show on ITV was one of our favourite looks from the series so far.

What did you make of Tulisa's choice this week?
