I am a size 18 and have been invited to boldly go where I've never been before and will no doubt ever go again - a Star Trek themed party this Saturday evening! 
I've searched online for something suitable and the only things coming up are £40-£50 and wouldn't fit me anyway! The women's outfits are like size 6-12 
Is anyone out there good at thinking outside the box as to who/what I can dress up as? I don't want to do something obvious like buy a set of pointy ears and go as Mr Spock. I would love to do something humorous if possible, in a spoof/piss take kinda way but I've been racking my brains and getting nowhere. AAaaaarrrrrggghhh!!! Please help!!
