The "spookiest" day of the year is coming, but you still haven't decided what to wear on Halloween? These most innovative and interesting cosplay costumes of all time can definitely inspire your trick-or-treating fun.
1. Luke Skywalker

Wow, this man absolutely nailed it! Even Mark Hamill himself would say he's THE Skywalker from Star Wars.
2. Mystique

Flawless execution! This costume is even comparable with the products of the high-paid Broadway costume designers. We can say she is the real Mystique!
3. Jafar

It is the most convincing Jafar cosplay that anyone could pull off. Try it on Halloween, and you will directly jump into the world of Aladdin.
4. Baby Groot

Wow, we can't imagine how long and difficult it was to make such a vivid and delicate mask. Look at the details of its head! The person who made this costume deserves a full scholarship to costume design school.
5. The Mad Hatter

It's excellent to design costumes and the matching equipment for disabled folks. On Halloween, they can go outside by taking their lovely and unique wheelchairs, just like the one in this photo.
6. Pennywise, The Clown

God, that grin is disturbing. Pennywise is a character in the movie It. This costume is so freaky that many children are bound to be scared by it on Halloween.
7. Steve And Robin

Robin is a new character that brings a ton to the table in Stranger Things season 3. The new dynamic duo is ready to scoop up more secret information, and all they need are just some scary Halloween makeup ideas.
8. The Nun

Ooh, this look is definitely nasty and scary. Before going to the Halloween party, we sincerely hope you can take those crazy teeth out!
9. Aziraphale And Crowley

These handsome folks do the Good Omen's cast justice. Aziraphale is from heaven, while Crowley is from hell. The pair must attract attention at the Halloween party.
10. Veruca Salt And Violet Beauregarde

These costumes are so cute and amusing. In the movie Charlie and the Chocolate Factory, Veruca Salt got a golden goose egg, and Violet Beauregarde chewed a piece of gum that turned her into a blueberry.
11. Imperator Furiosa

In the film, Mad Max: Fury Road, Furiosa is a war captain under Immortan Joe, and her costume can make you the coolest on Halloween.
12. Jon Snow And Thanos

What an amazing cross-cosmos meeting! HBO and Marvel can't make it true, but you can! Try their costumes on Halloween, and you will make history.
13. Elastigirl

Due to the popularity of The Incredibles films, the costume of Elastigirl is hot at the Comic-Con. Swing from buildings in those heels, and then you will be the center at the Halloween party.
14. Elsa

This one might be the best Elsa cosplay ever done. Everything is perfect here, including her beautiful eye color. Deck out with the costume on Halloween, and you will captivate the whole world.
15. Harley Quinn

It isn't the Suicide Squad version of Harley Quinn. The old version is more positive, while the new one is rebellious. They both are good choices for your Halloween costumes.
16. Inspector Gadget

This childhood classic tugs at our heartstrings. But the good thing is, this guy didn't have to go through hundreds of hours of painful surgeries to get these enhancements.
17. Widowmaker

This one is for all those Overwatch fans out there. The costume is absolutely flawless, perfectly executing all of Widowmaker's details, including all of her gear.
18. The Tethered, Us

It is another good idea for Halloween costume. The movie Us has won a ton of awards, and rightfully so. This cosplay is pretty spot on to the characters in the film.
19. Buzz Lightyear

The detail in this costume is impeccable. Try it on Halloween! The fans of Lightyear will admire you so much!
20. The Mask

Beautiful work! This is a pretty easy costume to put together, but the mannerisms that Jim Carrey uses are the key ingredient to a successful cosplay. Have any interests to try?
