Halloween Costume Guide
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.

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
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
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
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
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.
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.
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.
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.
