Quick Answer: John Constantine’s costume is a black trench coat over a white shirt and tie, finished with a lighter prop.
  • Black Trench Coat (essential)
  • Constantine’s Lighter (essential)
  • Long Sleeve White Dress Shirt
  • Black Necktie
  • Fake Cigarettes

Constantine hunts demons and half-breed spirits in Los Angeles while trying to buy his way out of a one-way trip to Hell. The black trench coat worn open over a shirt and tie is the item that makes the costume, everything else is detail. He is a niche pick outside fans of the 2005 film, since the character originated in DC’s Hellblazer comics decades earlier and looks quite different there.

  • 1 Black Trench Coat (essential)The black trench coat is the single piece that makes this costume read as Constantine instead of just a man in a suit. It needs to be long, plain, and worn open over the shirt and tie, never buttoned up.

  • 2 Long Sleeve White Dress ShirtA crisp white dress shirt underneath the coat keeps the silhouette formal and slightly out of place, which is the point. He dresses like he is going to a funeral, not a fight.

  • 3 Black NecktieA plain black necktie, worn loose rather than perfectly knotted, matches his slightly rumpled version of formal wear.

  • 4 Black Dress PantsBlack dress pants finish the suit underneath the coat. Any dark, fitted pair from your closet works.

  • 5 Constantine’s Lighter (essential)The lighter is a small prop, but it does a lot of work. Constantine chain-smokes through most of the film, and flicking a lighter open gives you something to do with your hands between lines.

  • 6 Black Oxford ShoesPlain black oxford shoes keep the whole outfit formal from the ground up.

  • 7 Constantine’s WatchA simple black or steel watch worn under the shirt cuff finishes the accessory list without pulling focus from the coat.

  • 8 Brown WatchA brown-strapped watch works as an alternate if you already own one and do not want to buy another accessory.

  • 9 Fake CigarettesConstantine smokes constantly on screen, and prop cigarettes let you copy that habit without an actual pack. It reinforces the character’s chain-smoking, world-weary attitude better than any single line of dialogue.

  • 10 Submachine GunA prop gun is optional and depends on the event. Some venues do not allow realistic-looking props at all, so check before you bring one.

How to Style the John Constantine Halloween Costume

Keep the coat open instead of buttoned, it needs to move when you walk. A too-perfect tie knot looks wrong on this character, loosen it slightly. Skip the tie entirely and the outfit reads as a random guy in a suit rather than a specific person. Add a lighter you flick open between sentences and people will place the reference even before the coat registers fully.

Constantine opens the film already dying of lung cancer and treats that fact with dark humor instead of despair. He tells Angela flatly that she should believe in the devil because the devil believes in her, then goes right back to smoking. That blunt, sarcastic delivery under real stakes is worth copying more than any single prop.

John Constantine Group Halloween Costume Ideas

Duo Idea

John Constantine & Doctor Strange

Excellent pairing of two occult specialists with completely different wardrobes. Constantine’s rumpled trench coat next to Doctor Strange’s cloak and amulet makes an easy visual split between street-level magic and cosmic sorcery. Both read clearly on sight, so the group photo does the explaining.

Duo Idea

John Constantine & Dracula

Strong pairing for a classic horror lineup. Constantine hunts exactly the kind of supernatural threat Dracula represents, so putting a hunter next to prey gives the group a built-in dynamic without needing a shared movie or comic.

Duo Idea

John Constantine & Freddy Krueger

Might work, but it leans on the group agreeing to an “iconic horror and occult figures” theme rather than any real connection between the two. Freddy’s bright sweater and glove clash hard against Constantine’s all-black formalwear, which can read as a mismatch instead of a deliberate contrast if nobody explains the pairing.

Duo Idea

John Constantine & Harry Potter

Might work, but only as a tongue-in-cheek “British wizard” joke, since the tone gap between the two is huge. Harry’s school uniform and round glasses read as youthful and bright next to Constantine’s chain-smoking cynicism, which is funny if the group leans into the contrast on purpose.

John Constantine Halloween Costume DIY Tips

Building the Look

Most of this costume is a normal formal outfit most people already own pieces of.

  • Shirt, tie, pants, belt, shoes: check your closet first, this is standard formalwear.
  • Coat: buy this one if you do not already own a plain black trench coat.
  • Watch: skip buying a new one entirely if you already own a plain watch in black or brown.

Props That Sell the Character

The lighter and cigarettes are cheap, but they carry more of the costume than people expect.

  • Lighter: keep it visible in your hand for photos instead of pocketed the whole night.
  • Fake cigarettes: use these instead of real ones, they photograph the same and do not require lighting anything.
  • Gun prop: check your venue’s rules first, some events ban realistic-looking props outright.

John Constantine Halloween Costume: FAQ

Start with the white dress shirt, black tie, and black dress pants, then add the black trench coat worn open, not buttoned. Finish with black oxford shoes and keep the lighter in hand for photos.

It works, but it leans on people recognizing a fairly specific 2005 film rather than a current pop culture reference. Fans of the movie or the Hellblazer comics will get it instantly from the trench coat and cigarette alone, but casual partygoers may just see a man in a suit unless you add the lighter and cigarette props.

In the 2005 film, Constantine tells Angela, “You should believe in the devil. He believes in you.” He also describes his worldview with the line, “Heaven and Hell are right here, behind every wall, every window, the world behind the world.”

No. Skip it if your venue does not allow realistic-looking props, which many do not. The trench coat and lighter carry the costume without it.

This guide is built around the 2005 film played by Keanu Reeves, which changed some details from the original Hellblazer comics, including the character’s usual blond hair and British accent.

The film uses his chain-smoking as a running detail tied to his terminal lung cancer diagnosis, part of his general world-weary attitude toward his own mortality.
