What your Bestival fancy dress says about you
A psychological analysis
The Enhancing
The outfit: The subject thinks to themselves 'I bet I'd look cute dressed as a cheerleader / cowboy / fireman' and selects their costume appropriately. Also comes with a less self-confident version i.e. 'I hate my squinty little eyes / knobbly knees, stringy facial wart, so I'll get a costume that covers them / it up'.
The wearer: Two equally narcissistic sides of the same coin, they're rather missing out on the creative and liberating possibilities of fancy dress. But then again, they look great. Liable to overdo the selfies and sulk excessively if it rains and their costume gets ruined.
