Tired of the annual standards? Here are a few ideas that are as easy to put together as they are original.

Doable Duos and Trios Costume Ideas

Britney Spears and K-Fed

For Britney: Apply an excessive amount of eyeliner. Throw on Uggs and a sundress that is questionably short and carry around two baby dolls. Drop them repeatedly and say "Gimme, gimme" all night.

For K-Fed: Find all the gold chains you own and put them on. Next, wear a pair of baggy jeans and a white T-shirt. Grow strange facial hair, and if your hair is long enough, corn row it. Try to rap all night, but make sure you're unsuccessful.

Andy Warhol and Edie Sedgwick

Andy Warhol: Find a bright blonde wig and bright-colored tight clothing (preferably a turtleneck and slacks). Wear an oversized pair of glasses and talk funny.

Edie Sedgwick: Go to your nearest vintage store and purchase a sequined or patterned mini-dress, go-go boots and a cropped blonde wig. Apply false eyelashes and loads of eyeliner.

Danny, Jesse and Joey from Full House

Danny: Wear a hideous button-down sweater over a collared shirt with pleated pants. Carry a feather duster.

Jesse: Wear blue jeans, a white T-shirt and a black vest over top. Apply lots of hair gel. Work the hair, baby!

Joey: Wear an old Hawaiian shirt with baggy khakis. Make sure to tuck in the shirt. Leave hair unstyled, carry around a woodchuck puppet and tell people to "cut it out!"

Effortless and Entertaining Ideas for Guys

Cast Away

Don't shave for a week. Rip off the legs of an old pair of khakis to make them shorts and throw on a dirty T-shirt. Finally, carry a volleyball with a red handprint face.

Dog the Bounty Hunter

Put on black jeans and a thick bulletproof-looking black vest with no shirt underneath. Tie leather bands around biceps and a utility belt around your waist. Hold or wear a "wanted" sign with a picture and information about a fugitive. Flash the "hang loose" sign inappropriately often.

Flava Flav

Find a plastic horned Viking hat and an old clock. Attach clock to a fake gold chain. Rap Public Enemy songs and repeatedly refer to yourself in the third person. Flava Flaaaaaaaaaaaav!

Lego
Take a large box and cut arm holes. Glue pieces of round sponge in symmetrical, horizontal lines. Paint the box and attached sponges red, yellow or blue. Wear over jeans and a white T-shirt.

Ren McCormack from Footloose

Who doesn't love Kevin Bacon in the '80s? All you need for this are snug jeans, a gray tank and Converse or some sort of old school lace-up sneakers. Spike up hair and dance all night, perhaps adding in a round-off or two.

Ideas for Girls

Deb from Napoleon Dynamite

Wear your hair in a side ponytail. Find a vintage, pink prom dress with poofy sleeves. Ask people if they want glamour shots.

Mary-Kate Olsen

Drive to Goodwill. Find a sweater three sizes too large and preferably black. Put on leggings, oversized sunglasses, dark eyeliner and deep red lipstick. Make sure hair is messy and tousled. If you look homeless, you have achieved the Olsen look.

Amy Winehouse

Find a long, dark hair wig and tease it until you've achieved her beehive look. Purchase "tattoo sleeves" and oversized fake eyelashes; make sure to apply an excessive amount of eye makeup. Put on skinny jeans, pumps and a black tank. Sing "Rehab" to anyone and everyone.
