Do you want to stick to a Disney theme for the costumes? If so, the simplest costume is one you purchase
The
Disney Store (online, at least) has them on sale right now and they do have adult sizes.
You could do a simple Dalmatian costume with white sweat pants and shirt. For the spots use a non-raveling black fabric, like a moleskin suede or knit and the paper backed iron-on adhesive (I think it comes in packages or by the yard). Iron the black fabric to the adhesive following directions then cut out your "spots" and iron them to the sweats in whatever patter looks natural. Finish it off with a red dog collar, a tail and some ears (on a head band or white stocking cap) and you're set. You could add a few spots and whiskers to your face if you wanted.
If you don't need to have the costumes be Disney related, one very inexpensive idea is to go as a bag of jelly beans. You just need a large clear pastic bag big enough for you to fit into or you could use some clear plastic sheeting. Cut holes for your legs in the bag/sheeting and for your arms if using a bag. Fill with inflated small balloons - the kind that are sold as water ballons work well, size wise. Finish it off by gathering the plastic around your neck and secure it (loosely, of course) with a big ribbon and bow such as candy stores often use on their prepacked "gourmet" jelly beans. This isn't a good costume if you need to sit down to drive but it isn't something you often see. A similar idea is to go as "white trash" - instead of ballons you fill the bag with white tissue paper that has been crumpled up a bit and use rafiie or twine to tie the bag closed. This one is a little better for sitting but a bit lumpy (yes, I used this idea one year
).
You could also wear robes, "jammies" and slippers and carry oversize stuffed animals. Make sure to mess up your hair and go as "kids on Christmas morning". One advantage of this is that you are ready for bed as soon as you get back to your room and you also don't have to pack a lot extra just for the cotume.
OK, last idea - go as tourists
Just see what others at the park look like on a non-costume day and exaggerate the look - maybe matching Disney shirts, hats, wear all your cameras, zinc oxide cream on the nose, etc.
