Halloween Costume Guide
Seventeen looks. One obsession. Dress like the most fashionable assassin on television.
Villanelle is a contract killer who treats assassination as an aesthetic project. She is also, inconveniently, the most stylish person in any room she enters. Jodie Comer plays her across all four seasons of Killing Eve, the BBC America spy thriller based on Luke Jennings’ Codename Villanelle novellas, and won the Primetime Emmy Award for Outstanding Lead Actress in a Drama Series for the role in 2019 (Wikipedia). The show ran from 2018 to 2022. There are seventeen looks on this page. Pick one.

Whatever look you pick, the first thing people notice is whether the clothes look chosen or assembled. Villanelle’s outfits are always chosen, even when they appear casual. The Prison Look needs to read as intentional monochrome, not like you grabbed the first green thing in the closet. The Plaid Look needs both patterns to be clearly committed to, not apologetic. If you look like you are not sure about the outfit, that is the only thing people will see.
At the party, Villanelle asks more questions than she answers. She is interested in people in the way a cat is interested in a bird. She leans in. She gives full attention and then withdraws it completely when something more interesting appears. She does not explain herself and she does not fill silences. If someone at the party asks who you are supposed to be, let the question sit for a second before answering. That is the character.
The Pink Dress at a real party
The ruffled mesh on the Pink Dress look catches on things. Bag straps, other people’s costume accessories, door frames. This is not a hypothetical; mesh ruffles are structurally designed to snag. Either carry nothing with a strap, or be ready to detach yourself from other people’s costumes multiple times over the course of the evening.
Pattern mixing requires commitment
The Plaid Look and the Striped Blazer Look both put two competing patterns in the same outfit. The moment you stop acting like it was deliberate, both looks collapse into “I got dressed in the dark.” Wear it like you planned it two weeks ago and have no doubts. Do not mention the patterns to people. If they notice, agree that it is interesting. Do not explain it.
Group Idea: Killing Eve Cast
Excellent concept for a group of four that has watched the show. The visual contrast between Villanelle’s fashion choices and the rest of the cast is built into the source material: Eve is in practical office clothes, Carolyn looks like she manages MI6 from a garden, and Konstantin always appears to be slightly untrustworthy in a comfortable blazer. Everyone knows who they are before anyone says a word.
Group Idea: Assassins
Strong group if everyone commits fully. The concept holds because each character has a distinct visual identity: Villanelle in fashion-forward outfits, John Wick in a black suit, Agent 47 in his signature red tie and barcode, Patrick Bateman in business casual with business card anxiety. People who know any one of these characters will get the group, and most people know at least one.
Group Idea: Lethal Characters
Might work, but this group requires everyone in the crowd to know all four characters. Villanelle, Love Quinn, Joe Goldberg, and Mia Wallace are all people who kill people and have very strong aesthetic identities. The connection is real. The problem is that Mia Wallace is from a 1994 film, Villanelle is from a 2018 series, and Love Quinn and Joe Goldberg are from a different show entirely. At a themed event for fans of dark, character-driven television, this lands. At a general Halloween party, you will be explaining the concept to almost everyone.
Group Idea: Same Actor
Might work, but only at a convention or in a crowd that specifically follows Jodie Comer’s career. Villanelle from Killing Eve is the recognized anchor. Millie Rusk from Free Guy has some recognition from 2021. Marguerite de Carrouges from The Last Duel and Kathy from The Bikeriders are niche enough that most people will just see four different women in unrelated costumes. If your group knows why this is a group, it is a clever concept. If you have to explain the actor connection to every person you meet, it stops being worth it.
Seventeen options is too many. Before you start sourcing anything, pick one look and commit to it. The question to ask is not “which is the best look” but “which look can I build with what I have or can get in time.”
The costume is half the work. The other half is the energy. Villanelle is genuinely delighted by people while also being completely unbothered by them. She is not anxious. She is not performing for approval. She is having a good time and would be having a good time whether anyone else was there or not.
Villanelle has seventeen distinct looks across four seasons of Killing Eve. Pick one and commit to it. The Pink Dress look is the most recognizable: a pink off-shoulder ruffled mini dress with black ankle boots. For something more wearable, the Chic Professor or Striped Blazer looks translate well to a real party setting without requiring much explanation.
Killing Eve ended in 2022 and recognition has thinned at general parties, but the Pink Dress look still reads on its own because the outfit is striking enough without context. Fans of the show will know immediately; everyone else will see a woman in a very good dress.
Two lines define her. The first, delivered with complete sincerity: “I was trying to make you feel better. I’m very good at this.” The second, which tells you exactly what kind of person she is: “I don’t want to be good. I want to be extraordinary.” Both work at a Halloween party.
Villanelle is played by Jodie Comer, who won the Primetime Emmy Award for Outstanding Lead Actress in a Drama Series for the role in 2019. The show ran four seasons on BBC America from 2018 to 2022.
The Prison Look is the simplest build: green t-shirt, green scrub jacket, green tactical pants, grey hair scarf. Everything is one color and most pieces are inexpensive. The Plaid Look is a close second: gingham shirt and checkered cropped pants is a two-item build.
The Pink Dress look. It appeared in promotional material and is the most-shared image from the series. Even people who never watched the show will connect it to Killing Eve if they have seen any marketing for it. The other looks require more context.
Yes, and it works well. The costume contrast between Villanelle’s high-fashion choices and Eve’s practical office clothes is the visual shorthand for the whole show. Anyone who watched Killing Eve will get it immediately.
