Halloween Costume Guide
From the boxing ring to the collar. Montana’s most unlikely priest.
Stuart Long punched people for a living, then found Catholicism, then got ordained, then got a degenerative muscle disease, and chose to frame all of it as something meaningful rather than just bad luck. That arc is the film. Mark Wahlberg plays him and also produced the movie, gaining a reported 30 pounds for the later scenes. The film was written and directed by Rosalind Ross and released by Sony Pictures in 2022 (Wikipedia). The real Stuart Long died in 2014 from inclusion body myositis, a progressive muscle disease he developed after his ordination.

The tab collar is the hinge. If it sits flat and visible at the throat above the robe, the costume works immediately. If it bunches, gaps, or disappears under the robe, the whole read softens into “person wearing black robes,” which is not the same thing. Check it before you leave the house. Adjust the robe so the collar shows cleanly at the centre neck. That detail is worth two minutes in front of a mirror.
There is a scene where Stuart is sitting in a hospital bed, unable to move much, and he tells another patient that suffering can be offered up. Not as a platitude. As something he has actually decided to believe because the alternative is that everything he went through was pointless. He says it like a man who has already done the argument with himself and come out the other side. That is the version of Stuart Long worth channeling at a party. Not the boxer. The one who already decided.
Keep the collar visible all night
The robe will shift at a party. The neckline moves, the collar tab gets folded under, and after two hours you are wearing a black robe with no visible priest collar. Check it periodically. A small safety pin inside the robe at the collar seam keeps the neckline from pulling. It takes thirty seconds to place and saves the whole costume reading correctly for the rest of the night.
The rosary is your prop and your conversation starter
Hold it rather than wear it. A rosary draped around the neck looks like an accessory. Held in one hand it looks like something you actually use, which is closer to the character. When someone asks who you are, the combination of the robe, the collar, and a rosary in hand is a more complete answer than the robe alone. It also gives you something to do with your hands at a loud party, which matters more than people expect.
Group Idea: The Montana Congregation
Strong group for a crowd that knows the film. The four main characters around Stuart cover the full emotional range of the story: the distant father who comes around, the girlfriend who converts alongside him, and the mother who never quite makes peace with what he became. All four costumes are civilian or clergy builds with no complicated props. The group lands clearly if people know Father Stu, and reads as “priest and his family” if they do not, which still makes sense.
Group Idea: Unconventional Men of Faith
Might work, but only at a party where people appreciate the premise. The concept is people who ended up in religious life via an unlikely route. Nacho Libre wrestled his way to it. Stuart Long boxed his way to it. The Nun is the odd one out since she is a horror villain rather than a believer, but the visual contrast is striking enough that the group reads as a joke with a clear punchline. It needs a crowd willing to engage with it.
Group Idea: The Mark Wahlberg Live-Action Roster
Strong concept for a group of friends who want a connective thread without wearing matching costumes. All four are Mark Wahlberg roles across different genres and years. John Bennett from Ted, Sully from Uncharted, and Cade Yeager from Transformers: Age of Extinction are different enough visually that the group does not look like a uniform. The joke lands best if one person in the group is willing to explain the connection to every person who asks, because not everyone tracks actor filmographies at Halloween parties.
Group Idea: The Stuart Monikers
Excellent group for a party that likes a dumb premise executed well. Four characters named Stuart or Stu across wildly different films, with nothing in common except the name. The joke is immediately obvious and requires no explanation. Stuart from Minions is the most recognizable. Stu Macher from Scream is the most niche. Stuart Long is the most unexpected. That spread actually helps the group because each character reads differently and the contrast is the whole point.
Group Idea: Cinematic Heavyweights
Might work, but the premise is tighter than it looks. All three characters have a complicated relationship with taking damage, physically or otherwise. Rocky is the most recognized costume in this group by a significant margin. Tyler Durden still lands with most crowds. Stuart Long is the one that needs context. The group works best as a trio where Stuart is the punchline: the guy who got through the same kind of punishment and became a priest instead.
This is one of the easier clergy builds because there is nothing custom or prop-heavy. The costume is almost entirely off-the-shelf. The difficulty is in making it look deliberate rather than generic.
Stuart is not a solemn priest. He came from a background of bars, boxing gyms, and bad decisions. The collar is new. The directness is not.
The clergy shirt is the item that makes the costume recognizable. Pair it with black dress pants, a black pulpit robe, black Oxford shoes, and a rosary. That combination reads as Father Stu immediately to anyone who has seen the film.
It works best at parties where people know the film. Father Stu had a strong theatrical run in 2022 and a loyal audience, but four years out it is not a broadly recognized costume at general Halloween events. Anyone who saw it will get it immediately. Anyone who did not will see a priest.
Two lines stick. The first is blunt: “Maybe God put me here to show that He can use anybody. Even a broken-down boxer from Montana.” The second is harder to shake: “Suffering is not pointless. It can be offered up.”
Mark Wahlberg plays Stuart Long. Wahlberg also produced the film and gained significant weight for the role to portray Stuart’s later years with degenerative muscle disease. Mel Gibson plays his father Bill Long, and Jacki Weaver plays his mother Kathleen.
Yes. Stuart Long was a real person from Helena, Montana. He was an amateur boxer who converted to Catholicism, was ordained as a priest, and died in 2014 from inclusion body myositis, a progressive muscle disease he developed after his ordination. The film was written and directed by Rosalind Ross.
Yes. The tab collar clergy shirt and the rosary together are enough to read as a priest. The robe adds formality and visual weight, but it is not essential if you want something easier to move in at a party.
