Tulisa or Alexandra? Vote for your favourite 'X Factor' outfit of the week

The X Factor isn’t just a search for the next pop superstar. It makes compelling viewing on the fashion front too thanks to the show's seriously stylish judges, Tulisa Contostavlos and Kelly Rowland

This week former X Factor winner Alexandra Burke stepped in as a last minute replacement for Kelly, who was off sick.

All eyes where on the two ladies as they dazzled on week four.

But which look do you think works best?

Each week, vote for the ensemble you like the most - and at the end of the series there will be a special poll to find The X Factor's reigning queen of style.
