Quick Answer: The Player 456 Halloween costume is four pieces built around one very recognizable tracksuit.
  • Squid Game 456 tracksuit (essential)
  • Squid Game 456 t-shirt underneath (essential)
  • White sneakers
  • Dalgona cooking set as prop

Seong Gi-hun is a broke, gambling-addicted father who enters a tournament of children’s games where losing means dying. He is the main character of Squid Game, the Netflix series that became a global cultural event almost overnight in 2021 and came back for a second season in 2024. The teal tracksuit with a player number is the costume. Number 456 specifically marks you as Gi-hun. Most people at any Halloween party will know what it is within two seconds of seeing it.

  • 1 Squid Game 456 T-ShirtThe base layer under the tracksuit. Wearing it underneath means you have a recognizable option if the jacket comes off later. The number 456 is on the chest, so even without the full tracksuit on top it still reads as the costume. Useful in warm venues where the full tracksuit is too much after a few hours.

  • 2 Squid Game 456 TracksuitThis is the essential item. The teal tracksuit with the player number on the chest is the most recognized visual from the show. It needs to be the right shade of teal and have the number clearly printed on the front. A tracksuit that is too dark or too bright loses the reference. The fit does not need to be precise but it should not look oversized.

  • 3 Dalgona Cooking SetThe prop that ties the costume to a specific scene. The honeycomb candy game in episode three is one of the most memorable moments from the show and most people will recognize what the Dalgona set references immediately. It gives you something to hold and interact with all night. Not essential, but I’d bring it. Explaining the umbrella shape you’re trying to carve out is a better conversation than explaining who player 456 is.

  • 4 White SneakersPlayers in Squid Game wear plain white slip-on shoes. Clean white sneakers are close enough. Check your closet first. Any white sneaker without a large logo or colored sole works fine here.

How to Style the Seong Gi-hun Halloween Costume

The tracksuit number is what people read first, and it needs to be visible from the front. A jacket that is zipped too high or a name tag covering the chest number means half the room is looking for a clue that isn’t there. Keep the jacket open enough to show 456 clearly, or leave it partially unzipped. The teal color does the broad recognition work. The number does the specific character work.

Gi-hun is not a composed person. He panics, he cries, he makes bad decisions and then makes slightly better ones. At a party, this means you react to things too strongly, you look like you’re running calculations on whether to trust the person next to you, and you hold the Dalgona set like it is a test you are about to either pass or fail. If someone asks you to do the Red Light Green Light pose, freeze mid-step, arms wide, one foot off the ground. You will not have to explain the costume to that person again.

The Number Has to Be Readable

If the tracksuit has a chest pocket or the zipper pull sits in front of the number, fix it before you leave. The 456 is the only thing separating you from every other person in a teal tracksuit at Halloween. Move the zipper, adjust the jacket, and check it in a mirror. Thirty seconds at home saves you repeating “I’m from Squid Game, the number one is on the chest” all night.

The Dalgona Set Is Worth Carrying the Whole Night

It is small, it is light, and it is the one prop that makes people immediately remember a specific scene rather than just a show. Challenge someone to carve out their shape without cracking it. They will fail. You will laugh. That interaction is better than any explanation you could give about who player 456 is.

Squid Game Players

Player 456 Gi-hun, Player 001 Oh Il-nam, Player 067 Sae-byeok, Player 218 Sang-woo, Player 101 Deok-su, Player 212 Han Mi-nyeo, The Front Man

The strongest group option by a wide margin. Everyone wears the same tracksuit and the number is the only differentiation, which means the group looks cohesive and coordinated without anyone needing to build a different costume. The Front Man is the one exception and is a harder build. You need at least three players for the group concept to land. Two people in tracksuits are just two people in tracksuits.

Squid Game Staff and Guards

Pink Guards, The Front Man, VIPs, Host/Recruiter, Red Light Green Light Mascot

This works well as a mixed group alongside players because the visual contrast between the teal tracksuits and the pink guard uniforms is exactly what the show looks like. The Red Light Green Light mascot is one of the more distinctive costumes available and reads immediately. The VIPs require more effort and the Host/Recruiter is a harder reference for a general crowd. The guards and the mascot are the two pieces worth prioritizing.

Famous Numbers

Player 456, Number 5, Numbuh 5, Agent 47

The theme is thin and the costumes look nothing alike, which means this group lives or dies on whether the crowd is willing to engage with the concept. Player 456 and Agent 47 are the two strongest visual anchors. Number 5 from Umbrella Academy lands for fans of that show. Numbuh 5 from Kids Next Door is genuinely nostalgic for a specific generation but niche for anyone else. A fun group for a very online crowd with a high tolerance for concept costumes.

Dystopian Games and Competitions

Player 456, Katniss Everdeen, Thomas, James Cole, Truman Burbank

A solid thematic group where most characters are individually recognizable without needing the group context to explain them. Katniss is the strongest anchor for a broad audience. Thomas from The Maze Runner has a loyal fanbase. James Cole from 12 Monkeys is a film person’s pick and will get recognition from the right crowd. Truman Burbank requires a name tag or a very specific prop to land. Player 456 sits comfortably in this group because the tracksuit reads immediately even without anyone knowing the theme.

Seong Gi-hun Halloween Costume DIY Tips

What to Buy vs. What You Already Have

This is one of the most accessible Halloween builds on the market. Three of the four items are either cheap or potentially already in your wardrobe. The tracksuit is the one piece worth buying specifically.

  • Squid Game 456 tracksuit: buy it, the specific teal color and number make this non-substitutable
  • 456 t-shirt: worth having as a backup for warm venues, or skip it if budget is tight
  • White sneakers: check your closet, any clean white sneaker works
  • Dalgona set: cheap and adds a lot to the costume, I’d buy it
  • The tracksuit alone is enough to be recognized, every other item is supporting

Playing the Character

Gi-hun is not stoic or composed. He is someone who is genuinely scared and genuinely trying. That is a different energy to play at a party than the typical “cool Halloween character” mode, and it is funnier when you commit to it.

  • Look at the Dalgona set like it is the most stressful thing in the room. Because in the show, it is.
  • His three quotes are emotional and specific. The one about his daughter is the one that lands hardest if you deliver it at the right moment and to the right person.
  • The Red Light Green Light freeze is the single most recognizable in-character move available. Use it once, hard, and at the right moment.
  • He trusts people more than he should and it keeps almost killing him. At a party, that reads as accepting every drink someone offers you. Do with that what you will.
  • If someone at the party is dressed as Sang-woo, do not turn your back on them. That is both accurate to the show and genuinely good advice.

Seong Gi-hun Player 456 Halloween Costume: FAQ

Four items: a Squid Game 456 tracksuit, a matching t-shirt underneath, white sneakers, and a Dalgona cooking set as a prop. The teal tracksuit with the number 456 on the chest is the whole costume. The Dalgona set is optional but makes the character immediately clear and gives you something to interact with at the party all night.

Three lines from the show that fans know well:

  • “It’s not your fault. We made a choice. We made our own choices.”
  • “If you kill us both, then what? Who are you going to kill in the next round? Do it if you can. But remember, it could be your turn next.”
  • “I was never a good father. But watching her grow up after she was born was the happiest time of my life.”

The second one is the most useful at a party. Say it to whoever is dressed as Sang-woo. If there is no Sang-woo, say it to whoever cut in front of you at the snack table. Both work.

Squid Game Season 2 dropped in late 2024 and kept the franchise at the top of Netflix conversation globally. The teal tracksuit with a player number is one of the most recognized Halloween costume silhouettes of the last five years. Most adults will place it immediately without needing any context at all.

No, but it helps. The tracksuit alone is recognizable. The Dalgona set adds a prop tied to a specific scene most people remember from the show and gives you something to interact with rather than just wearing a costume. If you are at a party where people will want to talk about the costume, it is worth having.

Yes. The t-shirt is a lighter option for a warm venue and the number is still visible on the chest. It reads less immediately in a crowd than the full tracksuit but it still clearly references the show. Add white sneakers and the character is still identifiable.

All players wear the same teal tracksuit. The number on the chest is the only thing that differentiates one player from another. 456 is Gi-hun, the main character. 067 is Sae-byeok, 218 is Sang-woo, 001 is Oh Il-nam. If you want to be a specific character rather than a generic player, the number is the entire distinction.

Seong Gi-hun is the main character of Squid Game, the South Korean survival drama on Netflix. He is a gambling-addicted father in debt who enters a deadly tournament of children’s games for a prize that would solve all his financial problems. He is played by Lee Jung-jae, who won the Emmy Award for Outstanding Lead Actor in a Drama Series for the role in 2022.
