How about other animals? I've done a horse and a buffalo. Get an appropriate color unitard. Do the tail like the tails they wear in the stageplay CATS...a thick rope/cord, and add fur to the end.
The idea for the horse came from Equus...guys in unitards with horseheads fixed on their heads. I used foam from the fabric store and formed it into the head, with ears and all, then fixed it on my head above so I could still see out.
The fabric store also has fake fur that can be used on the body. I'm thinking of getting fur for a lion costume, to build the mane and chest hair.
There are so many ideas that can be built on tights, leotards and unitards. Just get a white long-sleeved unitard with a white hood and go as a sperm cell! I've got a million of them (ideas and sperm cells!)!
