Halloween Costume Guide
The man who ended the war. The costume that requires a brief explanation at most parties.
Matthias Erzberger does not fire a rifle. He signs a document, and in doing so ends the war that the film has spent two hours refusing to let you look away from. He is the German Centre Party politician who led the armistice delegation in 1918, signing the Compiegne agreement that ended World War I (Wikipedia). In the 2022 Netflix adaptation directed by Edward Berger, he is played by Daniel Brühl. The film won four Academy Awards including Best International Feature Film. The costume is a tweed suit with period details, and recognition at a general Halloween party will depend almost entirely on how much the crowd watches international cinema.

The mustache and glasses together are what shift this from “man in a tweed suit” to a specific character. If either one is off, the whole read softens into generic period costume. The mustache needs to be dark, full, and correctly placed on the upper lip. If it sits crooked or starts peeling at a corner, that is the thing people notice first, and it makes the rest of the costume look unfinished. The glasses frame the face and add the bureaucrat read. Get both right and the suit does the rest of the work without needing to be perfect.
In the film, Erzberger sits across a table from Allied officers and signs a document while the front continues fighting just a few hours away. He is completely composed, which is either cold or just exhausted, and the film is not entirely sure which. That is the character at the party: someone who has made a decision no one else wanted to make, and is not looking for praise about it.
Carry a prop document
A folded piece of paper labeled “Waffenstillstand 1918” or “Armistice Agreement” gives you something to reference when someone asks about the costume. Most people will not immediately place Erzberger at a party. A physical prop closes that gap faster than a verbal explanation. It also gives you something to do with your hands, which matters more than people expect at loud events.
The mustache adhesive has a time limit
Stick-on mustaches hold well for roughly three to four hours on clean skin, then the edges start to lift. If you are at a long event, bring the adhesive backing or a small spirit gum stick. The mustache lifting on one side is the specific failure here because once it starts to peel, it draws more attention than if you had just taken it off. Check it around the midpoint of the night.
Group Idea: The Armistice Delegation
Strong group for anyone in a crowd that watched the film, because the contrast is the whole point: the man who negotiated the peace and the soldiers who lived the war, standing in the same room. Erzberger is the civilian in the suit; Paul and Kat are in uniform; Friedrichs is the general who chose to keep fighting until the final minute anyway. The tension between these four characters is what the film’s final act is built on. At a general party, it reads as a WWI group with one politician, which still works without requiring people to know the film.
Group Idea: The Burden of Leadership
Might work, but only at a party where people enjoy explaining their costumes, because the concept requires context to land. Four real historical figures who each made a single enormous decision that ended something. Oppenheimer is the most recognizable by a large margin right now. Churchill and Lincoln are iconic enough on their own. Erzberger is the one the group will spend time explaining. The concept is coherent in theory, but in practice it is four solo costumes standing near each other.
Group Idea: The Daniel Brühl Dossier
Might work, but this is a group concept built entirely for people who track actors across roles, and that is a narrow audience at any party. Zemo from the MCU is widely recognized. Niki Lauda from Rush is recognizable to film fans. Zoller from Inglourious Basterds is niche. Erzberger is niche. The concept only lands if someone in the group announces the conceit upfront, and even then it requires most of the crowd to be fluent in Daniel Brühl’s filmography. I would only attempt this at a film-nerd event.
Group Idea: Early 20th Century Power Brokers
Strong visual group because the period suits do a lot of shared work. Thomas Shelby is the most recognizable anchor here by far, and his presence helps the group read as intentional even if not everyone places Erzberger or Nucky. Gatsby is broadly known but requires commitment to the costume to read as Gatsby specifically. The group works at a general party because the 1910s-1920s suit aesthetic is coherent enough to hold together without detailed explanation.
This is one of the easier builds on the site because there are no props to fabricate, no armour, and no complicated makeup. The difficulty is purely in the period accuracy of the suit and the mustache adhesion holding through a full night.
Erzberger is not a loud character. He is a man who did an unpopular thing that needed to be done, and he knows the history will not be kind to him for it. That is the energy.
Start with the tweed suit, then add the cravat and round glasses. The stick-on mustache is what shifts the look from “early 20th century gentleman” to a specific character. Finish with a pocket watch and Oxford shoes, and you have the full Erzberger build.
It is a niche pick. The 2022 film won the Oscar for Best International Feature Film and had wide Netflix visibility, but Erzberger is a supporting character, not the lead. Most people at a general Halloween party will read this as “WWI-era German politician” and leave it there, which is fine if you are comfortable explaining the reference.
Two lines stand out. The first captures his position: “I am here to end the war, not to win it.” The second, delivered after signing the armistice, reflects the weight of what he has done: “The war is over. And yet it is not.”

Yes. Matthias Erzberger was a German Centre Party politician who led Germany’s armistice delegation in 1918. He signed the Armistice of Compiegne that ended World War I on November 11, 1918, and was assassinated by right-wing nationalists in 1921 (Wikipedia).
Carry a folded paper labeled “Armistice Agreement” or “Waffenstillstand 1918.” It gives you something to reference when explaining the costume and makes the character legible without any other context. The mustache and round glasses do a lot of the visual work, but the prop closes the gap for anyone unfamiliar with the film.
