Vincent Adultman from BoJack Horseman Halloween Costume Guide

A businessman. Definitely one adult. Do not ask about the broom.

Quick Answer: Vincent’s costume comes down to the oversized trench coat and fedora that supposedly disguise three kids as one adult.
  • Trench Coat (essential)
  • Black Shirt
  • Blue Pants
  • Fedora Hat (essential)
  • Fake Hand
  • Maroon Duct Tape (For The Hat)
  • Broom
  • Black Sneakers

Vincent shows up as Princess Carolyn’s boyfriend and insists he’s an ordinary businessman, even though he’s built like three kids stacked in a trench coat with a broom for one arm. The coat and fedora together are what make the joke work, since either piece alone just reads as a costume-shop detective. Alison Brie voices both Vincent and Diane Nguyen (Fandom), and he only appears in a handful of Season 1 and 2 episodes, so recognition depends on whether your crowd has actually watched that far into the show.

Vincent Adultman BoJack Horseman Netflix Trench Coat Bit
  • 1 Trench Coat (essential)This is the entire joke. A long, oversized brown trench coat is what turns a person into possibly three children standing on each other’s shoulders instead of just a guy in a coat. Get it too fitted and the whole bit falls apart, since the point is that it should look like it’s hiding something.

  • 2 Black ShirtPlain black undershirt, visible at the collar under the coat. Nothing fancy, it’s barely on screen in the show either.

  • 3 Blue PantsPlain blue jeans. Check your closet before buying a pair specifically for this.

  • 4 Fedora Hat (essential)The second half of the disguise. A gray fedora is what completes the kid’s-idea-of-a-businessman look, and it needs the red hatband to be accurate, which is what the duct tape below is for. A fedora alone without the coat just reads as a guy in a hat.

  • 5 Fake HandStands in for Vincent’s mannequin hand, one of his two arms in the show. Hold it slightly stiff and awkward rather than natural, since the whole point is that it doesn’t quite work like a real hand.
    See on Amazon
  • 6 Maroon Duct Tape ( For The Hat)Wrap this around the base of the fedora to fake the red hatband from the show. It’s a small detail, but it’s the kind of thing that tells someone who’s actually seen the character that you did your research.
    See on Amazon
  • 7 BroomHis other arm in the show, and the funniest prop on this list. Carry it like an actual limb rather than an actual broom, since the joke is that nobody in the show questions it either.
    See on Amazon
  • 8 Black SneakersThe show actually has him in blue Velcro sneakers, not black, so this is a color swap rather than an exact match. Check your closet first if you want to get closer to the real color.

How to Style the Vincent Adultman Halloween Costume

The trench coat is the first thing people register, and if it fits close to the body instead of hanging loose and oversized, the whole joke stops working, since the coat needs to look like it could plausibly be hiding three kids. The broom and fake hand only land if you actually hold them like arms, stiff and a little wrong, rather than carrying them like props you picked up on the way out the door. At a party the fedora with the hatband is what separates this from a generic trench coat costume, so if you skip the tape detail, you’re just someone in a coat and hat.

When BoJack spirals about life being a series of closing doors, Vincent pats his head with the broom arm and says, “Don’t be sad… Good horsey,” like he’s comforting a pet. Nobody in the show questions that his arm is a broom. Nobody questions much about Vincent at all, which is the entire point of the character.

Tuck the fake hand away between photos

Carrying both a broom and a fake hand all night means one of your actual hands is never free, which gets old fast when you’re trying to hold a drink or your phone. Tuck the fake hand into the coat sleeve and only bring it out for photos, so you’ve got a working hand the rest of the time.

Answer everything with “I did a business”

Answer every question about your night with some version of that line, no matter what the question actually was. It’s one bit, but it’s the whole character, and it works better the less you explain it.

Vincent Adultman Group Halloween Costume Ideas

Couples Idea

Vincent Adultman & Princess Carolyn

Strong pairing if your group knows the show, since their relationship runs through most of Season 2 and the comedy of a competent, exhausted career woman dating someone who might be three kids in a coat has real material behind it. Princess Carolyn’s page has the build if you want that half done right.

Duo Idea

Vincent Adultman & BoJack Horseman

Excellent duo. BoJack spends the whole show convinced Vincent is a fraud and nobody believes him, so putting the two side by side plays into that joke even without any dialogue. BoJack’s page covers his build if you want the full list.

Group Idea: BoJack Horseman Main Cast

Vincent, BoJack Horseman, Princess Carolyn, Todd Chavez, Diane Nguyen, Mr. Peanutbutter

Excellent group. BoJack and Princess Carolyn already have their links used elsewhere on this page, so here they’re just names. Todd, Diane, and Mr. Peanutbutter round out the main cast, and the range across a slouched horse, a golden retriever-coded dog, and a plain-dressed writer keeps five people from looking repetitive.

Group Idea: Iconic Comedic Impostors

Vincent, Mrs. Doubtfire, White Chicks, Mysterio, Buddy Pine

Might work, but this is a theme that only holds together if you say it out loud, disguised or fake identities played for comedy, since a trench coat kid, a British nanny in a fat suit, two guys as sorority sisters, and a Pixar supervillain have nothing visually in common. None of these four have pages here yet, so every build in this group is entirely on you.

Vincent Adultman Halloween Costume DIY Tips

Building the Look

Almost everything here is closet or thrift material except the tape and the fake hand, both of which are cheap.

  • Trench coat: thrift stores almost always have an oversized brown one somewhere, and oversized is actually correct here.
  • Shirt and pants: check your closet first, plain black and blue basics are common.
  • Fedora: buy one if you don’t already own a plain gray fedora.
  • Tape: buy this one. It’s cheap and it’s the detail that gets the hatband right.
  • Fake hand: buy this one, it’s a small, specific prop that’s hard to substitute.
  • Broom: you probably already own one.
  • Shoes: check your closet first, any black sneaker works even though the show’s are blue.

Playing Vincent at the Party

Vincent talks about business constantly and never seems to notice how strange that is.

  • When someone asks who you are, say “Vincent Adultman” and nothing else. Let them figure it out.
  • Answer every question with some version of “I did a business,” regardless of what was actually asked.
  • If someone asks about your arms, don’t acknowledge that anything is unusual about them.
  • His line to use: “Business-wise, this all seems like appropriate business.” Say it about literally anything happening at the party.

Vincent Adultman Halloween Costume: FAQ

Wear the oversized brown trench coat over a black shirt and blue jeans, add the fedora with a maroon tape hatband, and carry the broom and fake hand as your arms. The coat and fedora together are what make this Vincent instead of a guy in a trench coat.

Depends on the crowd. He’s a recurring joke character, not a main cast member, and he only appears in a handful of episodes across two seasons, so recognition is real among BoJack Horseman fans but won’t land at a general party. Expect “kid in a trench coat pretending to be an adult” to read fine on its own even without anyone placing the exact character.

Three lines cover him well: “I went to stock market today. I did a business,” his signature vague explanation for literally anything he did that day, “Business-wise, this all seems like appropriate business,” and “Don’t be sad… Good horsey,” which he says while comforting BoJack with his broom arm like it’s a completely normal thing to do.

Just for show. Nobody expects you to actually use it, the joke is carrying it like it’s attached to you rather than something you’re holding.

No, black sneakers work fine as a substitute. The coat, fedora, and props are doing the real identification work, so the shoe color isn’t something people will check.

A little. Carrying both means one hand is never free, so tuck the fake hand into your sleeve when you’re not posing for photos and only bring it out when you need it.

Yes, completely. It’s a trench coat, a hat, and a couple of silly props, nothing to explain away or tone down for kids.
