Cassian Andor Halloween Costume Guide

Spy. Rebel. Has been in this fight since he was six years old.

Quick Answer: The Cassian Andor costume is a grounded spy-rebel build where the parka and holster carry most of the recognition.
  • Military Parka (essential)
  • Belt Holster (essential)
  • Tactical Shirt
  • Durable Pant
  • Leather Messenger Bag
  • Black Ankle Boot

Cassian Andor runs missions for the nascent Rebellion using whatever cover story holds long enough to get him out. He is not a hero by nature; he is someone who made a decision and has been living with it ever since. The character appears in the Disney+ series Andor, created by Tony Gilroy, which serves as a prequel to Rogue One: A Star Wars Story (Wikipedia). Diego Luna plays him in both. The costume is functional, dark, and layerable, which makes it more wearable than most Star Wars builds.

  • 1 Military Parka (essential)This is the piece that makes people say “oh, Andor” rather than “generic military guy.” Cassian’s parka is dark, structured, and worn-in looking. Get one in a deep olive, navy, or charcoal. Avoid anything too clean or fashion-forward. The parka should look like it has been worn on a few bad nights already.
    See on Amazon
  • 2 Long Steampunk Gothic CoatAn alternative outer layer if the parka does not fit the look you are building. Works better for a more dramatic Cassian interpretation than for the grounded everyday spy version.
    See on Amazon
  • 3 Black WigOnly needed if your hair is not already dark and medium length. Cassian’s hair sits close to his head with no volume. Keep the wig flat if you use one.
    See on Amazon
  • 4 Hooded Leather JacketA leaner alternative to the parka for a different episode or scene from the show. Cassian cycles through a few outer layers across the season. This works if you want a slightly more streamlined build.
    See on Amazon
  • 5 Army Quilted VestA useful mid-layer if your venue is temperature unpredictable. Goes under the parka or stands alone as a lighter outer piece.
    See on Amazon
  • 6 Leather Messenger Bag (essential)Cassian carries a bag. It is one of his most consistent visual details across the series. A worn leather messenger bag cross-body is the right choice. It also gives you something to actually carry your things in, which makes it the most practical item on this list by a significant margin.
    See on Amazon
  • 7 Bomber JacketAnother outer layer option for a warmer venue or a scene-specific look. Pairs well with the tactical shirt if you are skipping the parka.
    See on Amazon
  • 8 Belt HolsterThe holster is the detail that shifts this from “generic dark outfit” to “person who is armed.” It does not need a prop blaster inside it to read correctly. The holster alone is enough. Wear it on the right hip at a slight forward angle.
    See on Amazon
  • 9 Tactical ShirtThe base layer. Plain, dark, no logos. This is what goes under everything else. Check your wardrobe first before ordering.
    See on Amazon
  • 10 Andor Costume SetThe official costume option if you want a matched build in one purchase. Sizing can be limited, so check availability early. Less flexibility than separate pieces, but less guesswork too.
    See on Amazon
  • 11 Andor Black Ankle BootDark ankle boots finish the silhouette. Any plain dark boot works here. No need to source a specific model.
    See on Amazon
  • 12 Durable PantDark, plain, functional. Avoid anything with visible branding or fashion cuts. These are working trousers, not fashion trousers.
    See on Amazon
  • 13 Brown BootAn alternative to the black ankle boot for a warmer-toned build. Works if your other pieces lean toward tan or olive rather than all-black.
    See on Amazon
  • 14 Cassian Andor Suit SetA more tailored interpretation of the Cassian look, closer to his undercover scenes than his field missions. Works if you want something you will wear again that still reads as Cassian to people who know the show.

How to Style the Cassian Andor Halloween Costume

The parka is what people clock first. If it reads as a military outer layer worn by someone who did not choose it for style, the costume is already working. If it looks like a fashion piece or a hiking jacket, you are wearing a dark outfit with a holster. The belt holster sits just below that first impression: it tells people this person is armed and does not want to be noticed. Those two items together establish the character before anyone reads your face.

In the show, there is a scene where Cassian is explaining himself to someone who wants to trust him but should not, and he is completely calm while doing it. He knows the cover story will hold because he has told it enough times that it sounds true. That is the energy he has at a party too. Not guarded. Not dramatic. Just someone who has decided what the story is and is not going back on it.

Wear the bag cross-body and put something in it

An empty messenger bag collapses against your side within an hour and starts to look like a prop. Put your phone, keys, and anything else you were going to carry anyway inside it. A bag with actual weight hangs correctly, moves the way a real bag moves, and draws the right kind of attention to itself. This is one of the few costume items that doubles as something genuinely useful at a party.

The holster position matters more than people think

A belt holster worn too far back on the hip disappears under the parka. Wear it forward and slightly angled on the right side, where it stays visible when you move. If the holster is hidden all night, one of your two essential pieces has stopped doing its job. You do not need anything in it. The holster reads on its own.

Cassian Andor Group Halloween Costume Ideas

Group Idea: Star Wars Rebellion

The Spark of Rebellion

Excellent group for a Star Wars crowd. Cassian, Jyn, Mon Mothma, and K-2SO are all connected by Rogue One and the early Rebellion, so the concept holds without needing explanation. K-2SO requires full robot costuming, which is the commitment test. If someone in the group wants to attempt K-2SO and they are actually going to do it properly, this is one of the better Star Wars group builds available. If K-2SO gets skipped or phoned in, the group works fine as a trio.

Cassian Andor Jyn Erso Mon Mothma K-2SO

Group Idea: Sci-Fi Rogues

Galactic Smugglers and Spies

Strong group concept based on visual contrast. Cassian is the most grounded-looking of the four; Han Solo brings the vest and blaster energy; Spike and Mal are from different universes but the aesthetic is close enough that the group reads as a unit. Recognition depends heavily on the crowd. At a general party, Han Solo carries most of the weight. At a sci-fi or genre event, all four land.

Group Idea: Same Actor

The Diego Luna Live-Action Roster

Might work, but only at a party where people are specifically going to get it. The concept is that every person in the group is a different Diego Luna character: Cassian from Andor, Miguel from Narcos: Mexico, Tenoch from Y Tu Mama Tambien, Jack from Flatliners. Most guests will not connect the thread without being told. That said, if your group knows the filmography and enjoys a concept that requires explanation, the individual costumes are all achievable builds. The group works as an inside joke more than a recognition moment.

Group Idea: Same Name

The Cassian Monikers

Might work, but the shared name is the entire concept, and shared names do not carry a group at a party. Cassian from John Wick: Chapter 2 is a recognizable character. Cassian from A Court of Thorns and Roses requires more niche knowledge. If your group finds the name coincidence funny and everyone commits to the costume builds, this works as a meta concept. If even one person is not fully in, it falls apart completely.

Group Idea: Reluctant Revolutionaries

Reluctant Dystopian Revolutionaries

Strong visual group if everyone builds the costume correctly. Cassian, Paul Atreides, Katniss, and Neo are all characters who did not particularly want to be symbols and became them anyway. The thematic connection is real, but it needs to be explained at most parties. Visually the contrast works: Neo in all black, Katniss in tactical gear, Paul in robes, Cassian in the parka. The group is interesting at a convention and needs context everywhere else.

Cassian Andor Halloween Costume DIY Tips

Building the Look

This is one of the more closet-friendly Star Wars builds. No prosthetics, no armour, no fabrication. The difficulty is keeping it grounded rather than letting it drift into generic military.

  • Parka: the key item. Dark, worn-looking, functional cut. Not a fashion jacket.
  • Tactical shirt and dark trousers: check your wardrobe before ordering. Most people have something close enough.
  • Belt holster: buy this. It is the detail that tips the costume from “spy energy” to “actually Cassian.”
  • Messenger bag: use one you already own if it is leather or leather-look. Any worn brown or black shoulder bag works.
  • Wig: skip it if your hair is already dark. Add it if the colour difference matters to you.
  • Official costume set: convenient, but the fit options are limited. Separate pieces give you more control.

Playing Cassian at the Party

Cassian does not perform. He has an answer ready for every question and delivers it without hesitation. The character is calm in proportion to how bad the situation is. That is specific and useful at a party.

  • When someone asks who you are: “Whoever I need to be tonight.” Do not elaborate.
  • His line “I’ve been in this fight since I was six years old” lands with zero context because it sounds true regardless of which fight someone thinks you mean.
  • The messenger bag gives you something to do with your hands at a loud party. Useful for a character who is always checking something or moving something.
  • Do not explain the show unprompted. If someone recognizes you, let them do the work. Cassian does not offer information he was not asked for.

Cassian Andor Halloween Costume: FAQ

The military parka is the most recognized piece from the show. Pair it with durable dark trousers, a belt holster, and a tactical shirt underneath. Add a leather messenger bag cross-body and black ankle boots. The holster and parka together are what get the character recognized.

Andor Season 2 aired in 2025, which gives the character stronger recognition now than at the show’s debut. Among Star Wars fans, Cassian is well known. Outside that group, the costume reads as a generic military spy, which is still a workable look even without the context.

Two lines define him. The first is from Rogue One: “I’ve been in this fight since I was six years old. You’re not the only one who lost everything.” The second is from Andor: “The Empire doesn’t play by the rules. They don’t care enough to learn. They don’t have to. You mean nothing to them.”

Cassian Andor is played by Diego Luna, a Mexican actor who first took the role in Rogue One: A Star Wars Story in 2016 and reprised it for the Disney+ series Andor, which premiered in 2022 (IMDb).

The official set gives you a matched look with less guesswork, but it is the pricier option and sizing can be limited. Building from separate pieces costs less, fits better, and leaves you with items you can wear again. The parka is the one piece worth getting right regardless of which route you take.

Yes. The Disney+ series Andor is a prequel to Rogue One: A Star Wars Story, following Cassian in the years before the events of that film. Diego Luna plays the character in both.
