I just found the coolest series of photos on the internet. It looks like a very ingenious couple that was taking part in a hair/wig show decided to subvert the system and create these enormous doll heads for the wigs to be placed on.
Completely wearable, the heads can be seen taking a stroll down the catwalk during the show. No word as to how heavy the enormous doll heads are, but they sure do look cool, and I am sure some high end fashion designer will be snatching up the idea.
