It's tradition for the female judges on the X Factor to be featured in style offs, however, with both UK and US versions currently filming their auditions, the style wars have gone international.
On her first day of auditions Demi rocked up in head to toe Topshop. Whilst the dress is unfortunately sold out the Snakeskin Leather Jacket and CJG Studback Peeptoe Pumps are still available.
Not her best look, for the Kansas auditions Demi once again opted for Topshop in a Strappy Button Midi Dress, CJG Lady Mama Booties, the harness is sadly sold out and her jacket is from Free People.
At the San Francisco Auditions Demi wore.... you guessed it, head to toe Topshop. I'm devastated that both dress and jacket are sold out. This is definitely her best look. I really love her dip dyed pink hair!
At the London auditions Tulisa rocked up in a skater dress by Felder Felder and Kandee ankle boots.
For the Liverpool auditions, Tulisa chose this questionable Lipsy dress and accessorised with a studded leather belt and cherry pumps.
At the Manchester auditions Tulisa opted for cute with an edgy twist in this truffleshuffle.com t-shirt, which is only £28.99
AND THE WINNER IS...
Clearly Demi! She looks cool and classy, I don't know what's going on with Tulisa but this skater-girl look is a little played out, she needs to get her act together before the live shows!
