Halloween Costume Guide
Ellie Williams is immune to the Cordyceps infection, which makes her either the most important person alive or the next person to die in a surgery room, depending on who you ask. The burgundy shirt over the grey long sleeve is the most recognizable build in 2026, and the arm tattoo is the detail that lands fastest for game fans. Bella Ramsey plays Ellie across the first two seasons of the HBO series, which premiered in 2023 (Wikipedia). Recognition at any Halloween party is high across all three builds, with the HBO version reading most broadly.

For the HBO build, the burgundy shirt worn open is the one item people will recognize first, and it needs to be open throughout the night. A buttoned burgundy shirt over a grey tee reads as a different outfit entirely. For the Part II build, the arm tattoo does the character-specific work that the grey layered shirts cannot do on their own. Without it, the costume reads as a generic grey-dressed survivor. For the Part I build, the red palm tee over the black long sleeve is specific enough that game fans will get it immediately, but the fake blood is what makes the build memorable at a convention.
In the HBO series, there is a scene where Ellie climbs a full-sized dinosaur statue in a museum, stands at the top, and shouts into an empty room about being on a motherfucking dinosaur. She has just come from a conversation about whether they should turn back, and she is choosing not to process it. That is the character in almost every scene: something difficult just happened or is about to happen, and she is choosing to be exactly this loud about something else instead. Bring that energy to whichever build you choose.
Managing the Part II weapon set at a party
Fourteen items sounds like a lot, and the weapon set is where most of it lives. At an indoor party, the bow and the machete become obstacles within the first hour. The practical approach is to arrive with the full set for photos at the beginning of the evening, then consolidate to the pistol and knife for the rest of the night. Both are small enough to holster or tuck away and visible enough to maintain the character read at close range. The tattoo and the scar do the heavy lifting once you are in conversation with anyone who knows the game.
Fake blood on the Part I build
Fake blood looks dramatic in photos and becomes a problem approximately forty-five minutes into any party. It transfers to everything it touches, including other people’s costumes, furniture, and door handles. If you want the David-chapter battle-worn version of Ellie, apply the blood to the hands and forearms only, not the face or the red tee. A small amount applied at the party rather than before arriving gives you more control over how much stays on what. Bring makeup remover wipes for the inevitable moment when someone grabs your hand without looking.
Couples Idea
Excellent couples concept with the strongest narrative weight in the franchise. The visual contrast between Ellie’s teenage casual build and Joel’s worn flannel-and-revolver look does the character work without any explanation. Anyone who has seen even one episode of the HBO series will recognize the pairing immediately. At any Halloween event in 2026 this is one of the most recognized father-daughter pairings in pop culture.
Duo Idea
Excellent duo with strong emotional resonance for Last of Us fans. Riley and Ellie’s story in Left Behind is one of the most recognized and discussed parts of the franchise, and their relationship is central to understanding everything Ellie does afterward. The two builds are visually distinct enough to read as separate characters and specific enough that game fans will recognize the pairing without a prompt. At a general party, Ellie carries the recognition while Riley rewards people who know Left Behind specifically.
Group Idea: The Last of Us Cast
Strong group for a Last of Us fan gathering or gaming convention. The five characters span the full emotional arc of the first game and its DLC, with Ellie and Joel as the central pairing and Riley, Tess, and Sarah as the losses that shape what both of them are running from. Ellie and Joel are the most widely recognized anchors at a general event. All five builds have dedicated pages linked here.
Group Idea: Iconic Survival Women
Strong group for a genre convention or a pop culture Halloween party. Katniss and Furiosa have the widest general recognition. Naru from Prey and Maggie Greene are well-known among genre fans. Ellie carries current cultural recognition following Season 2 of the HBO series, which puts her alongside Katniss as one of the two most immediately recognized characters in this group in 2026. The five builds are visually distinct enough that no two characters look like they came from the same show, which is what makes the group concept hold together as intentional.
All three builds share one underlying rule: the layering is everything. A single shirt on its own reads as a casual outfit. The layered combination is what makes each version character-specific. The backpack and footwear are consistent anchors across all three.
Ellie is loud when she is deflecting and quiet when she is actually affected by something. Most of the time at a party, she would be loud. The joke book is not a random character detail. It is what she uses when the silence gets too heavy.
Three builds are available. For the HBO look: grey long sleeve under a burgundy short-sleeve button shirt, medium wash jeans, black backpack, grey crew socks, maroon sneakers, and a flashlight. For the Part II look: grey work shirt, grey v-neck tee, Ellie arm tattoo, slit-knee olive jeans, grey backpack, and a full weapon set. For the Part I look: black long sleeve under a red palm tee, side bangs wig, skinny jeans, grey backpack, Uncle Sam pin, flashlight, fake blood, and grey high tops.
Yes, and it is one of the strongest recognition builds available for Halloween 2026. The HBO series brought Ellie to a mainstream audience far beyond the game’s existing fanbase, and Bella Ramsey’s version of the character is widely recognized. At any general Halloween party the HBO build reads immediately. At a gaming convention, all three builds land clearly.
Two quotes define her. The first is from the dinosaur museum scene in the HBO series: “Look at me. I’m on a motherf*cking dinosaur.” The second is her outburst to Joel in Jackson: “Everybody I have cared for has either died or left me. Everybody fucking except for you.” The first shows who she is when nothing is wrong. The second shows what she is protecting.
Ellie is played by Bella Ramsey, an English actor. More than 100 actors were considered for the role before Ramsey was cast. They learned an American accent and cut over 15 inches of hair for the part. Ashley Johnson, who voiced Ellie in the original games, also appears in the HBO series in a different role.
Ellie was exposed to a trace amount of Cordyceps during birth, when her mother was bitten. The infection that grew with her from birth produces a chemical messenger that tricks any new Cordyceps infection into thinking she is already infected, preventing the fungus from progressing. The Fireflies believed this could be reverse-engineered into a vaccine, which is the reason for her entire journey with Joel.
The HBO build. Bella Ramsey’s version of the character is the most widely recognized in 2026 because of the show’s mainstream audience. The burgundy shirt over the grey long sleeve with maroon sneakers and a backpack reads clearly to anyone who has watched the series. The Part II arm tattoo is the strongest recognition detail for game fans specifically, but it requires explanation at a general party.
No. The linked temporary tattoo approximates the moth design from Part II and is recognizable to fans of the game without needing to be exact. The tattoo is primarily relevant for the Part II build. For the HBO and Part I builds, Ellie does not have the moth tattoo, so skip it entirely for those versions.
