You could just zombie up with make up. If you want to go as Lady GaGa just get hold of some of that Crime Scene tape and leave little to the imagination.

I've nearly finished my costume and it's fucking ridiculous. It's a recreation of this: partywiththis.com/images/P/FlamingoRider%5B1%5D.jpg

only with a pink monster instead of a flamingo.

So it's got beyond the stage of just looking like a massive vag now?

only just. I stuffed it last night (fnar fnar)
and sewed the neck and head on so it's not just a pink furry teardrop with a hole in the middle now.

It kind of looks like a bright pink Cookie Monster.

The Crime Scene tape is a good idea
Except no-one wants me to leave little to the imagination
