We couldn't pass up the opportunity to mention Disney Princesses! Princess Jasmine arrived on the scene in 1992 and has become many peoples' favorite Disney Princess. She's intelligent, witty, advocates for herself, and has fantastic hair. There are plenty of Jasmine costumes for women and girls from both animated and live-action films.
6. Jedi Costume
Jedi or Sith? Jedi operate on the light side of the force, and they often carry green, blue, or even purple lightsabers! (Sorry if red is your favorite color.) They typically dress in neutral-colored tones, often brown, grey, and tan. If you're not dressing as any character in particular but want to be your own Jedi, brown robes like the ones worn by Obi-Wan Kenobi are a good starting point.
7. Jessica Rabbit Costume

"I'm not bad. I'm just drawn that way." Jessica Rabbit is a human toon character from Who Framed Roger Rabbit. She's one of many suspects, but in stark contrast with her appearance, she truly loves her husband and has a substantial moral center. (As opposed to only being in a relationship with Roger Rabbit for money and fame.) People who love sexy costume ideas will love dressing as Jessica Rabbit for the letter "J".
8. Jester Costume
There are a lot of similarities between jesters and clowns. They dress up in silly costumes with the purpose being to entertain people. Also, many Halloween costumes like to turn them scary, like this evil jester costume. If you love scary costumes but are hoping for something different from a scary clown or a horror movie character, perhaps a frightening jester costume would be a nice change of pace.
9. Jesus Costume
Do people frequently tell you that you look like Jesus because you're a guy with long hair and a beard? Lean into your looks by wearing a Jesus costume! We love to see all the fun and creative ways people dress as Jesus, such as riding a motorcycle or a skateboard dressed as Jesus Christ. If you can dress up your ride to match, that's even better!

Jessie and James always make a flashy entrance, complete with their opening monologue from the Pokémon TV series. You can win Halloween if you make a splash dressed as Team Rocket. Meowth, that's right!
13. Joan of Arc Costume
We love historical costumes that bring famous people back to life. Many women have fought for equality, including Joan of Arc. She rode with French forces and was later seen as a savior of France. Not only is this famous lady knight a great costume idea for Halloween, but she also works well for history projects. We love a versatile costume!
14. Jafar Costume
We're still not done with Disney! As much as we love the Princesses, Disney villains are great. They wear excellent outfits and often speak some of the best lines in their movies. Unlike some villains who openly oppose our heroes, Jafar keeps himself close to those in power while working behind the scenes to snatch it from under everyone's feet. He's such an iconic villain and a great choice for a letter "J" Halloween costume.
15. John Cena Costume
Plenty of sports figures have names that start with J, such as Jackie Robinson, Jeff Gordon, and James Harden. They all make excellent costume ideas, but we'll talk about one of the goats of wrestling—John Cena. Not only is he a decorated wrestler, but his career has shifted into an actor! Is there anything this man can't do?
16. John Snow Costume
Shop all Game of Thrones Costumes
In a cast as big as Game of Thrones, we have a case for several characters with names starting with "J". We couldn't mention all of them, but Jon Snow is one of our favorite character costumes. Initially given a rotten start in life, he kept his moral compass intact through some incredibly dicey situations. We also love his outfit, especially the fur-lined cape. You won't be chilly during Halloween this October!
17. Jockey Costume
Jockey uniforms are some of the boldest sporting outfits with bright colors and sharp patterns. Many fans watch from a distance, so we can see why they'd pick such eye-catching outfits! If you love sporting events like the Kentucky Derby and the Preakness Stakes, a jockey costume might be perfect. Don't forget a pair of tall black riding boots to help complete your costume!
18. Judge Costume
Do you like Halloween costumes that aren't restrictive? A judge costume would be perfect for you! The loose-fitting robe allows you to wear your own clothing underneath, and you can put it on and remove it as needed.

Jane Austen was a famous novelist who famously wrote Pride and Prejudice and Sense and Sensibility, among other books. Centuries later, they're still being read!

We'd hate to see such influential historical costumes confined to Halloween, so don't be shy about using them for school events, either!
21. Jovie Costume
In the Christmas movie Elf, Buddy falls in love with a jaded retail store employee, Jovie. The Christmas season can be rough on people, and she seems like she's gone through the wringer. However, his extreme Christmas cheer manages to help her find her joy again. This is a great character costume that starts with "J" for Halloween or Christmas—why not both?
22. Jack-o'-Lantern Costume
Pumpkin costumes have long been a Halloween staple, especially jack-o'-lantern costumes, These carved pumpkins are placed on porches to celebrate Halloween. If you're wearing letter costumes for Halloween, "J" for jack-o'-lantern couldn't be more fitting! These costumes come in the full range of sizes from infants to adult plus, making them incredibly accessible for everyone.
23. Jigglypuff Costume
The Pokémon franchise now has over 1,000 Pokémon species, but many of us still remember the original 151 well. Jigglypuff was a beloved character in the anime series, putting people and Pokémon to sleep and drawing silly faces on them with her hidden marker microphone. We love that there's a Jigglypuff kigurumi so you can dress as one of our favorite pink Pokémon. It's so cozy!
