x-factor is edited so the contestants are from many auditions.why its put together like this i think is so you get a good mixture on ever x-factor that goes out,that why both women are wearing different clothes and hairstyles
In one segment last night,they showed a member of the production team announcing to the audience that the judges were taking a short break for a wardrobe change. I suspect the filming sessions are very long...and this gives the impression that auditions happen over many days,when they don't actually.
