Do you put together your own costume? Not store bought?

Scarecrow (I was this last year, pretty simple to throw together at home)
A man (I was a biker dude one year, wore Bruce's leathers and painted a goatee on my face. Or you could attempt to do the half man half woman)
Shark bitten surfer (I was this a couple years ago. Just used my wetsuit and make up.)
A ghost
Vampiress
