Search for "easy" or "last-minute" Halloween costumes on Pinterest and you'll turn up a loooot of sexy cats, sexy cat-burglars and sewing projects only a Mormon mommy-blogger would deem DIY. If you want a costume that requires little-to-no advance planning and also covers your upper thighs, you're pretty much left to your own imagination. Or this post! I'm not saying these are the best low-effort, DIY costumes—But maybe they might jump-start your imagination. And if not? Just put on a wig. No one questions a girl in a wig.

Winona Ryder in 'Reality Bites'
If you've got brown hair, a red shirt and round glasses, you can go as Winona Ryder in Reality Bites. Bonus if you go around acting whiny and entitled all night long.
Janeane Garafalo in 'Reality Bites'
Red lipstick, awesome sunglasses and a baby-doll dress and you're Janeane Garafalo's Reality Bites alter-ego. With the 90s so hot right now, you can probably find all this stuff at Forever 21.
A Person in a Cut-Out Skull T-Shirt
Take an old t-shirt and cut it into an creepy scull face. It says: I'm not really trying, but I do have fine motor skills.

Elaine from 'Seinfeld'
Put your first job interview suit (or any terrible 90s leftovers) to good use as Seinfeld's Elaine.
Kerry Washington in 'Scandal'
It helps if you have a long white coat, but all you really need is some tailored business attire to pull off Scandal's Olivia Pope.
80s Pat Benatar
Do you have an ill-thought-out Urban Outfitters or American Apparel purchase from the past few years? Chances are you can make it into a badass Pat Benatar costume. Just be sure to get the snarl down right.
Step 1. Buy a mask. The end. If you're feeling ambitious, you could try holding an anti-Scientology sign.
The Gloss suggests you find a red windbreaker, add jeans and a white tee and slick back your hair and you're James Dean in Rebel Without A Cause.
Throw on some yoga pants, a sports bra and a tank-top (bonus points if it's neon) and you can go as a yogi. This gives you a good opportunity to go around stretching and doing poses all night, if you're into that sort of thing. Plus you get to go barefoot all night, which is a worthy goal in any Halloween costume.

On Halloween, anything orange and black reads as pumpkin. Throw together whatever orange and black clothing you've got, and top it off with some pretty pretty pumpkin-esque makeup. Sam Escobar (pictured here) has a nice pumpkin makeup tutorial at the gloss.
If you're too self-respecting to wear a superfluous headband, bandeau top and 37 bangles at the same time in real life, do it on Halloween!
Borrow your boyfriend/brother/dad's tie and vest, put on some khaki's and you're Woody Allen's most famous heroine.

A Down Marker
Costume idea via my lovely little sister. All you need is different colors of felt (pro tip: the headpiece will, however, make getting in and out of cars difficult).
Put on an old prom dress, flip your hair at the ends, do some glam make-up and make this face all night.
Red, white & blue + big hair and you're the badass Texas gubernatorial candidate.
Kermit the Frog
Draw eyeballs on two ping-pong balls and attach them to the top of a headband. After that, a green turtleneck or some green bunting around your neck are all you need. Blogger Rad Megan offers a great tutorial.

Break out old ballet shoes or just go the tights and leg-warmers route. Add a leotard and a hoodie (bonus for an off-one-shoulder sweatshirt) and you're an off-duty ballerina.
A Givenchy Glitter Model
Glitter up your face and go as one of the models from Givenchy's 2013 Paris Fashion Week show.
