A bit late, but hey, we threw our costumes together yesterday after 3p.m. to go out last night. "I feel your pain" to all the peeps who had costumes people didn't understand. I was a Desperate Housefly. My husband was the Great Pumpkin. Both costumes were homemade and cost less than $15 total for new materials.
My costume was an apron I had with pantyhose tied to it. The hose were stuffed with plastic grocery bags attached for the extra legs. I sewed things representing each housewife on the extra legs (fake Ritalin for Lynette, a spatula for Bree, a clutch purse for Gabi, and a paintbrush for Susan). I also had wings made from coathangers and plastic wrap, and antennae from pipe cleaners, eyes from floral foam balls covered in foil and attached to a headband. I also made a strand of pearls. Mr. Anthropologal carved his own pumpkin head and I cut a hole in a $3 black sheet, sewed some snaps so it would fit snugly and voila - costumes!
