Cute & Clever
Tree & Koala
Tree: Brown pants, brown shirt, leaves made of green cardboard or fabric, pinned to your clothes.
Koala: Gray pants, gray shirt, gray face paint with a black oval around your nose. Remember to give the tree plenty of hugs, so people can see you in your "natural" habitat.
Adam & Eve
For the brave couple.
Both: Cut large leaves out of green construction paper or green fabric. Go as nude as you're comfortable with and strategically pin or tape the leaves to your garments. If you fear you'll be cold, purchase flesh colored leggings and long-sleeve tops to go under the leaves. Bonus: Carry around a sack of apples and offer them to people.
Adam: Apple in hand (or pocket).
Eve: Wear a rubber toy snake around your neck.
Andy Warhol & Marilyn Monroe
Andy: Black turtleneck, round sunglasses and white hair. Really committed folks can bleach their hair, others can wear a white wig or buy white hair spray.
Marilyn: Pale Pink foundation, aqua eye shadow, crimson lipstick, yellow wig or hair spray, a la the famous pop-art portrait Warhol created of Marilyn after her suicide. Wear a white or black halter-top dress, like this one from American Apparel, which can be styled several ways.
Hot Dog & Bun
Hot dog: Brown shirt, brown pants, brown toboggan hat, brown shoes. Use red and yellow fabric paint to draw squiggly ketchup and mustard lines vertically up and down your body. Bonus: Glue on small squares of white cardboard to simulate chopped onions.
Bun: Cheap foam mattress pad with holes cut out for your arms.
Goldilocks & Bear
Goldilocks: Blond wig with a bow. Blue, yellow or pink peasant dress of any kind. Apron. White ankle socks and Mary Janes. Bonus: Carry a spoon.

Little Red Riding Hood & Wolf

Wolf: Furry, pointed ears, fangs, gray or brown face paint, furry tail. Or, simply, wear a Wolf Blitzer T-shirt.
Artist & Painting
Artist: Paint-splattered clothes (overalls if you're going modern or a black cape if you're going old-fashioned), painting palate (can be real, or made from cardboard), paint brush.
Painting: Take a large, rectangular cardboard box and cut a rectangle out of one side, so there's about two inches of cardboard left around the edges. Then put the box over your head so you're looking out of the hole you just cut—you're suddenly inside a frame. The painting can dress up like a famous painting (think Mona Lisa or Girl With A Pearl Earring) or be an original work of art.
Sexy Lady Frankenstein & Doctor Frankenstein
Doctor Frankenstein: A white lab coat, disheveled hair, plus a stethoscope, lab goggles, gloves or any other medical instruments you can round up. Bonus: Spattered blood on the lab coat.
Sexy Lady F: Green face paint from forehead to cleavage, black lipstick and fake stitches on your forehead. (Your brain was just replaced, after all.) Wear an oversized blazer over a sexy little black dress. Bonus: Black fingernail polish, green stockings, a white streak in your hair, using a white or gray hair extension or white hair spray.
