James from James and The Giant Peach - pretty standard clothing.

Old pants and shirt with a couple of holes/patch work spots and some straw out the bottom of the pants = scarecrow from Wizard of Oz

A bear - all brown/dark clothing and some ears and a brown face = Goldilocks and the Three Bears

light clothes and the egg cup from a carton of eggs painted pink with two black nostrils - use elastic to fasten around face. A curly tail from some pipe cleaners... and you have yourself a pig from The Three Little Pigs

Some boots, jeans, and a pirate style shirt (read button up shirt usually white), pretend sword, long tail (think old pantyhose stuffed with newspaper and painted black or orange) = Puss in Boots

Sorry, that's all I've got right now...
