check out mooseburger, and costumes by Betty to get some ideas. Look at Disney and Reniassance outfits. When you get an idea you may need to combin patterns, for ex., Rooney's actually came from a pj. pattern. Sue's old one I drew out on news paper and made my pattern, but I sew a lot, Sue's new is basically a sqare dance dress, Sally's is a square dance skirt, home made vest and good will shirt. [I like it the best, but doesn't have pockets I need, so I'm looking at revamp her as well ] Flower's costume is 3 patterns combined, sleeves from a clown costume, top from a dress, and skirt from a poodle skirt pattern. Hope this gives you some ideas.
