Halloween is by far the most fun and creative holiday of the year. It's an entire day filled with excessive amounts of candy, quality time with your friends and family, and most importantly: costumes. For most of us, halloween costumes consist of a few accessories and fun make up, or something that came out of bag that was ridiculously over-priced. However, halloween carries a completely different meaning to celebrities. Many of them spend hours upon hours along with copious amounts of money to make sure they stand on this spook-tacular evening. Here is a look at some of the best getups that hit the red carpet last weekend.

Taylor Swift

T-swift definitely embraced the Halloween spirit as Olaf on the latest stop of her 1989 World Tour. Joining her on stage for a guest performance was Idina Menzel in her classic blue Elsa gown. The two ladies gave a live sing-a-long performance of Fronzen's hit song "Let It Go". How precious.

Heidi Klum

Heidi killed the costumes game at her 16th annual Halloween bash in NYC this year. After 10 long hours of work, she was unrecognizably transformed into Jessica Rabbit from Who Framed Rodger Rabbit?

I have one word: SLAY.

Demi Lovato

For MTV's Girl Code Live Halloween special, Demi took a literal spin on Fetty Wop's hit single, Trap Queen. Her royal look was complete with actual traps attached to her cape. I see what you did there.

Justin Bieber

The Biebs dressed up as Will Ferrel's character, Jackie Moon, from the smash comedy "Sem-Pro". Maybe it's just me, but those shorts are turning up the heat and giving me some Bieber-fever.

Kim Kardashian

Thank you Kim, for reminding us that you have a sense of humor and for not taking yourself too seriously. This throwback to her pregnant 2013 fashion fail at The Met Gala was a nice trip down memory lane.

Katy Perry

Katy gave us not one, but two side-splittingly hilarious costumes this year: A mike drop and a Cheeto. Who even comes up with that kind of stuff? So just to recap, not only is Katy gorgeous, rich and talented, but also funny and creative. Not fair.

Ellen DeGeneres

Ellen hosted the Halloween episode of her talk show as Karla Kardashian and broke the internet. As if we all needed yet another reason to absolutely love her. I would say Ellen won halloween this year.

"Since I'm the younger sister I get all the hand me downs so these are Kim ’s Shape Ups I'm wearing, this is Khloe 's old blouse, and the booty is all mine."

"I'm the lesser known Kardashian sister, my name is Karla Kardashian with a K, we're known for our double K's. These are double K’s too, by the way."
