Legally Blonde: Elle Woods (Played By Reese Witherspoon)

I feel like a lot of girls, myself included, wanted to grow up to be Elle Woods. a.ka. the fashion student-turned-lawyer who looks fabulous in hot pink. Reese Witherspoon leads the cast of Legally Blonde and plays the peppy Harvard law student. She rocks the courtroom and her fits, and you’ll be the talk of the Halloween party if you go dressed as Elle Woods.

Mean Girls: Regina George (Played By Rachel McAdams)

Regina George really is the most iconic mean girl of them all, so much so that even Lindsay Lohan wanted to play her. She led the Plastics in their high school escapades and was the root of most of the problems in the movie. However, Rachel McAdams's character had the best outfits in the movie. Just by grabbing some bright pink clothes, turning up the sass and saying iconic lines like, “Get in, loser, we’re going shopping,” you are bound to have one of the most fetch costumes.

The Devil Wears Prada: Miranda Priestly (Played By Meryl Streep)

If you are looking for a scary character, but in an unconventional way, look no further than the fabulous and intimidating Miranda Priestly from The Devil Wears Prada. Granted, this one's a bit of a cheat since the movie came out in 2006, but this is too good to pass up. The editor-in-chief of Runway Magazine is a soft-spoken, yet aggressive boss who runs the magazine with style. Played brilliantly by Meryl Streep, Miranda makes the perfect costume that is chic and easy to put together.

I grew up wanting to be exactly like Mia Thermopolis, the normal girl-turned-princess of Genovia. If you're like me, you can live out your princess dreams by recreating Anne Hathaway’s lovely schoolgirl look from the first movie. If you want to spice it up, throw in a tiara and some sunglasses to pay homage to the classic movie poster.

Miss Congeniality: Gracie Hart (Played By Sandra Bullock)

I think this classic Sandra Bullock character would be so fun for a Halloween costume.

This movie was such a unique and fun mystery at a pageant, and Gracie was the best part of the whole movie. Dressing up as Miss Congeniality would for sure be a super fun Halloween costume.
