For Saturday's X Factor show Nicole shunned her usual OTT sexy outfits in favour of a chic, sweet Alexander McQueen rose skater dress and high plait. We love the giant gold accessories and matchy pout but those stumpy-clumpy nude platforms were a big mistake.
On Sunday the ex-PCD babe slipped back into her comfort zone in a sheer-panelled Alpana and Neeraj gladiator dress with Topshop pointy courts. Showy and totally hot.
On Saturday Tulisa saw Nicole's rosey McQueen dress and raised her a green corseted pencil dress teamed with Fendi cut-out heels. Not bad but Nicole's lush textured frock won this bout for us.
Tulisa's Sunday best consisted of a strapless Milly LBD, cinched in with a golden belt and paired with gorge Goth heels. Potentially our fave onstage Sunday look.
But wait just one darn minute. What's this!? Tulisa was snapped after the Sunday night show had ended wearing a stunning mint green metallic number. This should totes have been her Saturday look.
