Quick Answer: The Allison costume is a bright, jewelry-heavy build where the orange curly wig does most of the recognition work.
  • Orange Curly Wig (essential)
  • Mustard Jeggings (essential)
  • Deep V Neck Crop Top
  • White Skinny Belt
  • Pearl Necklace and Pearl Choker
  • Knuckle Ring Set
  • Airsoft Pistol

Allison is a cheerleader in a Satanic cult who handles getting shot in the chest by worrying about her chest, not the gunshot. She appears in both Netflix horror-comedies directed by McG: The Babysitter (2017) and The Babysitter: Killer Queen (2020, Wikipedia). Bella Thorne plays her both times. The costume is loud enough to be fun at a party even if nobody recognizes the character, which at a 2026 Halloween event is a real possibility.

Allison The Babysitter Killer Queen Bella Thorne
  • 1 Deep V Neck Crop Top (essential)The crop top and the jeggings together are what makes this read as Allison rather than just a casual party outfit. The deep V neckline is the specific detail to look for. Apply the self adhesive skinny fabric (item 3) along the neckline once you have it on. Without that trim, the neckline looks unfinished compared to Allison’s on-screen look.

  • 2 Orange Curly Wig (essential)This is the item that gets people across the room. The orange curly wig is the most visually distinct part of Allison’s look and the one people who know the character will recognize first. Make sure you have a wig cap underneath. Curly wigs shift more than straight ones, and a shifted wig at a Halloween party is its own kind of costume.
    See on Amazon
  • 3 Self Adhesive Skinny FabricApply along the neckline of the crop top. It is a small detail but it gives the top a more finished look that matches the character’s screen appearance. Check the adhesive is skin-safe before applying directly to your body.

  • 4 Airsoft PistolAllison carries a gun during the film’s later sequences. The prop adds context for people who know the character. Check your venue’s prop policy before bringing it. Many Halloween events do not allow realistic-looking weapons even when clearly plastic.

  • 5 White Skinny BeltWorn at the waist over the jeggings or the crop top. It ties the two pieces together. One of those items that is easy to overlook in planning and obviously missing when you do not have it.

  • 6 Mustard JeggingsThe mustard color is specific and it matters. Neutral black or grey jeggings lose the character reference entirely. The mustard shade is the bottom half of this costume. If you can only get one piece right after the wig, get this one right.

  • 7 Knuckle Ring SetAllison wears a lot of rings. A knuckle set covers multiple fingers quickly without hunting for individual pieces. Wear it on one hand or spread across both.
    See on Amazon
  • 8 Hoop EarringsMedium-to-large hoops, nothing delicate. Check your jewelry box before ordering.
    See on Amazon
  • 9 Hoop Nose RingA small detail but part of Allison’s look. A clip-on version works fine if you do not have a nose piercing.
    See on Amazon
  • 10 Pearl NecklaceLayer this with the pearl choker (item 11). Allison wears both at once. Together they give the jewelry stack the right amount of excess for the character.
    See on Amazon
  • 11 Pearl Choker NecklaceWear this at the same time as the pearl necklace. The layered pearl look is one of Allison’s signature details.
    See on Amazon
  • 12 White Skate ShoesFlat, plain white shoes. Check your closet first. Most people own something close enough.

How to Style the Allison Halloween Costume

The orange wig is the first thing people see. If it is flat, lopsided, or the wrong shade of orange, the rest of the costume does not matter. Style the wig before you leave, not in the car. Allison’s hair is big and curly, and a deflated curly wig just looks like an unfinished costume. The mustard jeggings are the second checkpoint: get them in the right color and the outfit reads as a specific character. Get them in a generic color and you are just a woman in a crop top.

In the film, Allison gets shot during a chaotic cult ritual and her most urgent concern is whether anyone will still find her attractive. That is the whole character in one scene. She is not performing meanness, she is not playing a villain with an agenda. She is just operating on an entirely different set of priorities than everyone around her, and she has no idea that this is unusual. That is the energy to play at the party.

Layer the pearl jewelry correctly

The pearl choker sits close to the neck. The pearl necklace hangs lower. Both go on at the same time. If you wear only one, you get half the look and it reads as unintentional rather than styled. The jewelry stack is one of the more recognizable details from the character’s design, and it is also the easiest thing to forget in the rush of getting ready.

Know your venue before bringing the airsoft pistol

Some Halloween events have strict no-prop-weapon policies even for obviously plastic props. Check before you pack it. The costume works without the gun. It does not work if you get turned away at the door and have to leave the prop in your car for the entire night, which is both annoying and slightly defeating the point.

Allison Group Halloween Costume Ideas

Couples Idea

Allison & Cole (The Babysitter: The Survival Couple)

Excellent couple dynamic for anyone who has seen the films. One person is trying to survive the night. The other person is actively trying to stop that from happening. The tension is built in and easy to play without saying a word. Cole has no dedicated page on CostumeRealm, so his costume requires building from scratch.

Allison Cole

Duo Idea

Allison & Melanie (The Babysitter: Killer Queen — Friends Turned Enemies)

Strong duo if both people know the sequel well. Allison and Melanie are friends at the start of Killer Queen until the film reveals Melanie joined the cult and has been manipulating Cole. The betrayal angle gives you something to play at a party beyond just “two girls from the same film.” Melanie has no dedicated page on CostumeRealm.

Allison Melanie

Group Idea: The Babysitter Cast

Allison, Cole, Melanie, Violet, Phoebe

Strong group for a horror fan crowd. At a general party, recognition will be inconsistent. The films are off major streaming platforms and were not the kind of cultural moment people remember unprompted five years later. That said, the cast has visual variety and the group concept makes sense to anyone who watched either film. Violet has a page on CostumeRealm; the other characters are build-from-scratch.

Group Idea: Iconic Horror Survival Girls

Allison, Grace, Ziggy Berman, Riley, Dr. Rose Cotter

Might work, but this group mixes recognition levels. Grace from Ready or Not and Dr. Rose Cotter from Smile are well known. Ziggy from Fear Street has a solid fanbase. Riley from Talk to Me is strong with horror audiences. Allison sits at the bottom of that recognition ladder for most people. The group works at a dedicated horror event. At a general Halloween party, some of these costumes will need explaining.

Allison Halloween Costume DIY Tips

Building the Look

This is one of the easier builds on the site. No armour, no complicated layering, no specialty makeup. The difficulty is in getting the color palette right and making the jewelry stack feel intentional rather than random.

  • Orange curly wig: do not skip the wig cap. Curly wigs slide.
  • Mustard jeggings: the shade matters. Mustard, not yellow, not brown.
  • Crop top: the self adhesive fabric trim on the neckline is a small detail that makes a real difference.
  • Pearl jewelry: both necklaces, at the same time. Layer them.
  • White skate shoes: check your closet first. Most people own white sneakers that are close enough.
  • Airsoft pistol: optional. Know your venue policy before deciding.

Playing Allison at the Party

Allison is not a villain with a plan. She is a narcissist who got mixed up in something bigger than she understood, and she handled the threat to her life by being annoyed about it. That is a very specific and very fun character to play.

  • When someone points out your costume is from a lesser-known film: act slightly offended that they do not know it.
  • If someone asks what happened to your character in the film: “I got shot. It was very rude.”
  • Her line about the nipples is the one most fans quote. Say it only if the crowd is going to find it funny, not just loud.
  • She is never scared. Surprised sometimes. Annoyed often. Never scared.

Allison Halloween Costume: FAQ

Start with the mustard jeggings and deep V-neck crop top. Layer on a white skinny belt, add the orange curly wig, and carry the airsoft pistol. The pearl necklace and knuckle rings finish the look. The cheerleader-gone-cult-member energy matters as much as the clothes.

If you are going to a party with horror fans who watched Netflix around 2017 to 2020, yes. At a general Halloween party, recognition will be patchy. The films have no current streaming home and were not award-season conversation starters, so most people will read the costume as “curly-haired girl with a gun” rather than “Allison from The Babysitter.”

Two lines define her. The first, after getting shot in the chest: “Who is going to want to suck on my nipples?” The second, while threatening Cole with a knife: “You still think I’m pretty?” Both deliver the same joke: Allison is completely unconcerned with the situation everyone else is panicking about, and very concerned about something entirely different.

Allison is played by Bella Thorne in both The Babysitter (2017) and The Babysitter: Killer Queen (2020), both directed by McG and released on Netflix. Thorne and Robbie Amell, who plays Max in the same films, previously appeared together in The DUFF (2015).

Allison is a member of Bee’s Satanic cult. The group makes a blood pact in exchange for getting what they each most want. Allison’s wish is to become a journalist, which says something about her ambition even if her methods are difficult to recommend.

Skip it if the venue does not allow props. The costume reads fine without it. The orange wig and mustard jeggings carry the recognition. The pistol adds character context for people who know the film, but it is not what makes the look identifiable.

Yes, and it is the most obvious pairing in the film. Cole is the protagonist trying to survive the night while Allison and the rest of the cult try to stop him. The dynamic is straightforward to play. Cole has no dedicated page on CostumeRealm yet, so that costume requires building from scratch.
