Alan Garner from The Hangover Halloween Costume Guide

He spiked the bachelor party drinks with roofies he thought were ecstasy and spent the rest of the movie pretending he had not done that. He won $82,400 at blackjack in the same evening, which he considers unrelated.

Alan Garner spikes the bachelor party drinks with roofies he mistook for ecstasy and spends the following 24 hours not mentioning this while helping the group solve the consequences. The shaggy brown wig and beard are the most important items in this build. The Hangover was directed by Todd Phillips and released June 5, 2009 (Wikipedia). Zach Galifianakis, who plays Alan, made it his breakout mainstream role after years of stand-up comedy (IMDb). Recognition at a general party is reliable for anyone who watched it as a teenager or adult.

Alan Garner The Hangover Zach Galifianakis Wolf Pack
  • 1 Brown Hangover Wig & Beard (essential)The shaggy brown wig and matching beard are the most recognizable physical features. Both need to come from the same set so the color and texture match. A wig purchased separately from a beard will usually read as mismatched. The hair should be long, unstyled, and clearly specific to this character rather than just a generic brown wig.

  • 2 Classic Black Baby Carrier (essential)The front-facing baby carrier is the prop that turns a shaggy casual look into specifically Alan from The Hangover. Without it, the wig and beard read as a general scruffy character. With the baby doll inside, there is no ambiguity. Buy a front-facing carrier so the doll is visible to people approaching you from the front.

  • 3 Polarized Aviator Sunglasses for MenOversized vintage demi-tortoise aviator frames. Alan wears these throughout the film and they became a brief fashion trend after 2009. On the face or pushed up on the forehead, both work. At an indoor night party, push them up rather than wearing them on your face the entire evening.
    See on Amazon
  • 4 Layette Baby DollThe baby for the carrier. The group names the baby Carlos. If you can source infant-sized novelty sunglasses, put them on the doll, which is what Alan does in the film. A realistic-looking doll reads better than a clearly toy baby.
    See on Amazon
  • 5 Human Tree Men’s T-ShirtThe grey graphic tee with the anatomical human head morphing into a forest tree line. This is the shirt Alan wears during the morning-after investigation and it is sold specifically as Hangover merchandise. People who remember the film closely will recognize it. Wear it loose and untucked.
    See on Amazon
  • 6 Sechunk Canvas Messenger Shoulder BagAlan’s brown canvas bag, which he insists is a satchel rather than a purse, and which Indiana Jones also has. Wear it across the body, not over one shoulder. The bag is a conversation prop as much as a costume item.
    See on Amazon
  • 7 Metallic Beaded NecklacesAlan wears several metallic beaded necklaces layered together in the film. Multiple necklaces worn together are the correct look rather than one single necklace.
    See on Amazon
  • 8 Men’s Dark Brown BeltStandard brown leather dress belt threaded through the utility pants. Check your own wardrobe first.
    See on Amazon
  • 9 Men’s White SneakersAlan wears white sneakers in the film. Check your closet before buying these.
    See on Amazon
  • 10 Men’s Relaxed-Fit Utility PantLoose-fitting, practical pants that read as comfortable rather than casual-stylish. Not skinny jeans. Alan’s pants look functional rather than fashionable, which is the intended aesthetic.

How to Style the Alan Garner Halloween Costume

The wig and beard together are what read from across a party. If the wig is too neat or too dark, or if the beard clearly does not match the wig in color, the whole build reads as “man in a wig” rather than a specific character. The baby carrier with the doll inside is the second item that confirms the costume. Without it, a shaggy brown wig and casual clothes could be any number of characters. With it, anyone who has seen the film places Alan within two seconds.

Alan climbs to the roof of Caesars Palace and gives a toast to his new friends Phil and Stu, whom he has known for approximately six hours. He explains that he considers himself a one-man wolf pack, and that having met Phil and Stu he has chosen to expand his wolf pack to four wolves. He does not mention that he spiked the drinks earlier in the evening. He is completely sincere about both things.

Set Up the Baby Carrier Before You Arrive

The carrier straps take a few minutes to adjust correctly and doing it in a venue parking lot while in the wig is a worse experience than doing it at home. Strap the carrier on, position the doll, and confirm the doll is secure before leaving. The doll will shift during the night. Check it periodically. A baby doll dangling sideways from a chest carrier reads as a different costume entirely.

Keep the Satchel Quote Ready

The canvas messenger bag is a conversation piece for people who know the film. When someone comments on it, the correct response is “It’s not a purse, it’s a satchel. Plus, Indiana Jones has one.” Deliver it with genuine defensiveness rather than as a punchline. Alan is not joking when he says this. He means it as a clarification, not a joke, which is where the humor comes from.

Couples Idea

Alan & Cassie

Might work, but Cassie only appears in The Hangover Part III, where Alan meets her at a pawn shop while searching for Mr. Chow’s whereabouts. Most people who recognize Alan from The Hangover are thinking of Part I specifically, so the pairing requires knowledge of the third film. If your partner wants to do a Hangover couple and only one of you wants to be in a shaggy wig, Cassie is the cleanest option, but prepare for people to ask why Alan brought a stranger to the Vegas bachelor party.

Duo Idea

Alan & Phil Wenneck

Strong duo from the core friendship of the film. Alan idolizes Phil and spends most of the trilogy copying his mannerisms and appearance. Phil is the more put-together member of the pair, which gives the duo a visual contrast between Alan’s shaggy casual look and Phil’s slightly more pressed appearance. People who know the film will recognize the specific dynamic between the two characters.

Group Idea: The Wolfpack

Alan, Phil Wenneck, Stu Price, Doug Billings

Excellent group for a crowd that has seen the film. These four are the direct cast from the Las Vegas bachelor party that starts the whole story. Phil is the confident one in a button-down, Stu is the anxious dentist in whatever he woke up in, Doug is the groom who goes missing for the entire movie, and Alan is the one in a shaggy wig with a baby strapped to his chest. The visual range across the four is good and the group has a clear identity.

Group Idea: 2000s Comedy Movie Characters

Alan, Ron Burgundy, Ricky Bobby, Derek Zoolander

Might work, but the visual range across these four is enormous and the connection is loose. Ron Burgundy is in a burgundy suit with a mustache. Ricky Bobby is in a racing jumpsuit. Derek Zoolander is in something intensely fashionable. Alan is in a shaggy wig holding a baby. The group holds together as “quotable 2000s comedy characters” to people who know all four films, but the unifying concept is thematic rather than visual and needs to be explained to most people at the party.

Alan Garner Halloween Costume DIY Tips

Building the Look

This is one of the more thrift-friendly builds on the site. Most of the clothing items can be sourced second-hand. The two items worth buying new are the wig and beard set and the baby carrier, because both need to function correctly through a long night.

  • Brown shaggy wig and beard: buy new as a matched set. Color consistency matters.
  • Black baby carrier: buy new. A working carrier holds the doll securely. An old or broken carrier will drop the baby, which is not the comedic impression you want.
  • Aviator sunglasses: thrift stores often carry these. The oversized vintage frame is the right shape.
  • Baby doll: toy stores or online. Realistic is better than obviously a toy. Tiny novelty sunglasses for the doll: optional, worthwhile.
  • Human Tree t-shirt: sold as Hangover merchandise online. Buy new.
  • Canvas messenger bag: thrift or use one you already own.
  • Metallic beaded necklaces: party supply stores or online. Cheap.
  • Brown belt: check your wardrobe.
  • White sneakers: check your wardrobe.
  • Utility pants: thrift stores always have these.

Playing Alan at the Party

Alan is earnest. He is not performing sincerity. Every strange thing he says, he means completely. The humor comes from the gap between how reasonable he thinks he is and how he appears to other people, and he is not aware of the gap at all.

  • When you meet someone new, tell them you tend to think of yourself as a one-man wolf pack and that you are now choosing to expand it to include them.
  • “Tigers love pepper. They hate cinnamon.” Deliver this as a helpful fact, not a joke.
  • When someone mentions Indiana Jones or bags, launch into the satchel defense. Mean it.
  • The baby carrier gives you an immediate conversation opener. Name the doll Carlos. If someone asks to hold the baby, you can go either way on that.
  • Alan occasionally refers to himself as a card counter. If someone challenges you to a game at the party, commit to this fully.
  • He is warm. He genuinely likes people. The shtick only works if the underlying warmth is real.

Alan Garner Halloween Costume: FAQ

Brown shaggy Hangover wig and beard set. Classic black baby carrier with a baby doll inside. Polarized aviator sunglasses. Human Tree graphic t-shirt. Canvas messenger shoulder bag across the body. Metallic beaded necklaces layered together. Dark brown belt, relaxed-fit utility pants, and white sneakers. The wig and beard paired with the baby carrier are the two items that create recognition.

Yes. The Hangover (2009) remains one of the most quoted comedies of its era, and the baby carrier plus shaggy wig combination creates recognition for almost anyone who has seen it. The build is also cheap and comfortable, which are not small advantages for a costume you will wear for several hours.

“You guys might not know this, but I consider myself a bit of a loner. I tend to think of myself as a one-man wolf pack.” “Tigers love pepper. They hate cinnamon.” “It’s not a purse, it’s a satchel. Plus, Indiana Jones has one.” These three are the most deployable at a party and cover most recognition situations.

Carlos. The infant in the film was played by triplets Grant, Avery, and Connor Holmquist. Grant Holmquist returned four years later to play the older version of the same baby in Part III.

$82,400. Alan reads a book on card counting before the film and applies it successfully at a high-stakes Vegas blackjack table during the climax of the first film, winning enough to pay off their debt to Mr. Chow.

Alan is the brother-in-law of Doug Billings, whose bachelor party starts the events of the film. He considers Phil and Stu his best friends from the moment they meet and considers the four of them a wolf pack. He is also the person who spiked the drinks that caused the situation, which he does not volunteer during the wolf pack toast.

Baby doll. A realistic-looking doll reads correctly for the costume. If you can source infant-sized novelty sunglasses, put them on the doll. Alan puts tiny aviator shades on Carlos in the film.
