Katy Perry wearing a lovely shiny metallic-blue PVC mac on 'American Idol'. For most of the programme she is sitting down as a one of the panel and you only get to see the top half of her mac. However, at 5 minutes and 17 seconds into the clip, she stands up and you get to see the full length of her lovely mac for about 10 seconds. Enjoy! https://www.youtube.com/watch?v=a7X_xKpMV-4

Stunning! Is Katy Perry wearing a latex dress underneath it?

You could well be right Taurus - it might be a latex dress (hard to see really). It could possibly be a lycra one too. Who knows?
