Halloween Costume Guide
Two looks, one hat that does all the work. The 2023 Ridley Scott film gave this character a new face — Joaquin Phoenix’s version — and the costume is more accessible than it looks.
Napoleon Bonaparte commands armies, crowns himself Emperor of France, and treats Empress Joséphine with the emotional range of a man who has never once been told no. Ridley Scott’s Napoleon (2023) puts Joaquin Phoenix in the role, and the film’s two main costume looks — the campaign greatcoat and the full imperial regalia — are both recognizable and buildable. The bicorne hat worn sideways is the only thing that matters. Everything else is context.

The hat is what people read first, and it has to be sideways. A bicorne worn front-to-back at a Halloween party is a pirate, an admiral, or a question mark. Sideways is Napoleon, immediately, to anyone in the room who has ever seen a painting or a poster. If the hat shifts to the front during the night, the costume loses its only clear identifier. Check it twice before you leave and once more when you arrive.
Joaquin Phoenix plays Napoleon as a man who is very aware of how small the room makes him look and deeply uninterested in pretending otherwise. At a party, that translates to standing slightly apart from conversations, watching rather than joining, and keeping your delivery flat and quiet. The sword gives you a reason to stand at a slight angle, which is more comfortable than it sounds after two hours on your feet.
The Hat Orientation Problem
Pin or bobby-pin the hat to your hair or wig before you go out. An unsecured bicorne at a crowded party will rotate forward by hour two without you noticing. Once it’s front-to-back, the costume stops reading as Napoleon and starts reading as something from a pirate-adjacent clearance rack. Two pins at the temples, placed before you leave, fix this for the whole night.
Campaign Look vs. Imperial Look — Pick One
Mixing the two looks makes the costume harder to read, not more impressive. The campaign look is the greatcoat, white trousers, plain bicorne, sword, and riding boots — no crown, no cloak. The imperial look is the gold-embroidered coat, king’s cloak, and crown. Decide before you buy. Both are recognizable on their own. Halfway between the two is neither.
The French Empire
This is the strongest option for a group that has all seen the film and wants historical accuracy. The dynamic between Napoleon and Joséphine is the emotional center of the 2023 film, so that pairing reads immediately to anyone who’s seen it. Wellington and Alexander I give the group its political weight. Four people, four very different costumes, one clear theme. The problem is that Joséphine’s period gown and Wellington’s British military uniform both require real effort. If one person half-commits, the group reads as a history class field trip.
Historical Cinematic Commanders
This works because every character here is widely recognized from a film most adults have seen. The costumes are different enough that the group doesn’t look like a uniform lineup. Conditional only because King Leonidas requires an actual commitment to the look — you know what that costume asks of a person. Everyone else is fully covered head to toe.
The Phoenix Portrayals — Same Actor
This only works at a party where people care about who plays the character, not just the character itself. Joker and Johnny Cash will land with almost everyone. Commodus from Gladiator will land with the right crowd. Theodore Twombly from Her requires someone to explain what a Joaquin Phoenix film festival group is doing at a Halloween party. Worth it if your group finds that funny. Not worth it if they don’t.
The Napoleons — Same Name
The concept is genuinely funny and takes about five seconds to explain to anyone who doesn’t get it immediately. Napoleon Dynamite is widely recognized and easy to costume. Napoleon Solo from The Man from U.N.C.L.E. is a stretch — the 2015 film did not leave a lasting mark. The Animal Farm pig is a creative build but you’re going to explain it a lot. Works best as a small group that enjoys the joke more than it needs external validation.
Pint-Sized Power Trippers — Niche
Half the party won’t get the theme without it being explained, and explaining the theme is the thing that kills the theme. The individual characters are all recognizable, but the connecting concept — short men and women with too much authority — is a meta-joke that works in a caption, not at a crowded party. Gaston, the Red Queen, and Joffrey are all strong individual costumes. The group framing is weak. Do this if the group wants to do it. Don’t do it expecting strangers to put it together.
The campaign look is cheaper and easier to assemble. The imperial look is more visually striking but requires more pieces. Before purchasing anything, pick one. Here’s what each build needs:
The Joaquin Phoenix version of Napoleon is not the theatrical, chest-puffed historical caricature. He’s contained, slightly sulking, and convinced he is the most important person in any room. That’s easy to play and it costs nothing.
The core build is the military coat with gold epaulettes, white trousers, a bicorne hat worn sideways, and a sword prop. For the imperial look, add the embroidered emperor costume, king’s cloak, and crown. The bicorne hat and the sword are the two items that make the costume readable from across the room. Everything else adds accuracy.
No quotes were provided in this guide’s brief, and the 2023 film does not have a single catch-phrase the way some costume films do. Napoleon Bonaparte left behind a well-documented record of real lines, including “An army marches on its stomach” and “Impossible is a word found only in the dictionary of fools.” At a party, the Joaquin Phoenix version is better served by tone than by a specific line — quiet, flat, and completely certain.
The 2023 Ridley Scott film gave the character a cultural refresh, and Joaquin Phoenix’s version is referenced enough that most adults will place the costume. The bicorne hat does most of the recognition work. Without it, you’re a man in a military coat — which could be anyone from the last three centuries of European history.
The campaign look: grey double-breasted greatcoat, white trousers, plain black bicorne, riding boots, sword. The imperial look: ornate gold-embroidered coat, red sash, heavy epaulettes, king’s cloak, crown. Both are recognizable. The campaign look is easier and cheaper to build. The imperial look is more visually striking in photos.
Yes. Without the hat, the costume reads as a historical general, a soldier, or a very formal party guest. The sideways-worn bicorne is the single detail that says Napoleon specifically. It is not optional.
The Napoleon French Emperor Costume bundle (item 7 in the list) is the most efficient single purchase. It covers the coat, trousers, and sash. Add the bicorne hat, epaulettes, and sword and you have a complete costume for well under $100. The cloak and crown are extras for the full imperial look — not required.
Tall riding boots, dark brown or black. Napoleon wore knee-high riding boots in his military appearances throughout the film. The knight boots (item 11) and the brown riding tall boot (item 12) both work. Avoid anything with a modern sole or toe shape — it will read immediately against the period coat.
Joaquin Phoenix plays Napoleon Bonaparte in Ridley Scott’s Napoleon (2023). The film follows Napoleon from the execution of Marie Antoinette through his military rise, his coronation as Emperor of France, and his obsessive relationship with Empress Joséphine. Vanessa Kirby plays Joséphine.
