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.
