Halloween Costume Guide
Ten items centered on stacked jewelry and a braid. A costume that rewards people who know the film and requires a brief introduction to everyone else.
Mollie Burkhart is an Osage woman at the center of Martin Scorsese’s Killers of the Flower Moon (2023), played by Lily Gladstone. The film is about the systematic murder of Osage Nation members in 1920s Oklahoma for their oil rights. Mollie loses her family one by one while the people responsible are still in her home. The jewelry is the most visible part of the costume. Most people at a party will not place it on sight, so be ready for that.

The jewelry is what people see first, and it has to be fully layered before you put on the shawl. If the shawl goes on first, it buries all four necklace and choker pieces and you’ve lost the most recognizable part of the costume. Drape the shawl over everything at the end, loose enough that the jewelry at the neck is still visible. If the shawl covers the chokers completely, the costume reads as a generic period look.
Mollie does not perform for the room. She is a woman watching what is happening to her family with the full knowledge that she cannot stop it. At a party, that means you are quiet in a way that is not shy. You don’t explain the costume unless someone asks. You don’t try to be recognized. If someone does place it, the conversation they want to have is a serious one, and that is a genuinely good conversation to have at a Halloween party.
Layer the Jewelry in the Right Order
Start with the pendant necklace at the longest length, then add the multi-strand black necklace, then the chokers at the neck. If you put the chokers on first and try to thread necklaces under them, everything tangles. Five minutes of patience putting them on in sequence will save you ten minutes of untangling at the venue.
The Braid Extension Needs to Be Pinned, Not Clipped
A clip holds at the start of the night. By hour two at a busy party, it has shifted or come loose. Take two bobby pins and anchor the extension to your actual hair above and below the clip. The braid hangs down your back all night, which means people walking past will knock it. Pin it like you know that is going to happen.
The Osage Nation Conspiracies
This is the strongest option for a group that has actually seen the film. The dynamic between the four characters is the entire story, so it plays naturally without needing setup. The problem is recognition: outside of people who watched Killers of the Flower Moon, most partygoers will not know who any of you are as a group. Commit to this only if your crowd saw the film or you don’t mind explaining.
1920s Crime and Ambition
The 1920s setting holds this together and each of the other three is broadly recognized. Mollie is the odd one out in terms of recognition, which actually works thematically: she is the one person in this group who is a victim of the era rather than a beneficiary of it. Conditional, because it works better at a crowd that watches prestige TV and classic films than a general party.
The Mollys — Same Name
Honestly, this only works if someone makes a sign. The name connection is not visible in the costumes and the characters have nothing else in common. That said, the individual costumes are all manageable builds, and if your group enjoys the meta joke more than landing recognition, it is a low-pressure concept. Molly Davis from Toy Story is the stealth risk: her costume is just a regular girl’s outfit, which means she needs the sign more than anyone.
Oil Boom Tragedies — Niche
This is a niche concept and you should know that going in. Killers of the Flower Moon, There Will Be Blood, and Giant are all films about oil, greed, and American violence in the early 20th century, which is a tight thematic thread. But outside of serious film people, this group will need the full explanation every time. Jett Rink from Giant is the weakest recognition link. I’d only do this at a film-crowd party where that kind of conversation is the whole point.
The jewelry pieces and the braid are what you need to order. The blouse, skirt, and shawl have a good chance of already existing in your closet or a thrift store. The boots are the wildcard: a plain flat ankle boot in a dark tone works as a substitute if you don’t want to order specifically.
Mollie is a quietly furious person who has learned to show very little of it. That is not a difficult character to play for a few hours at a Halloween party, but it requires some commitment. You are not performing grief. You are performing the containment of it.
Ten items: silver teardrop earrings, a long braided ponytail extension, a pendant necklace, a black multi-strand necklace, a black layered choker, a multi-layer beaded choker, a long-sleeve blouse, a pashmina shawl, Native American boots, and a vintage A-line long skirt. The layered jewelry and the braid are the two essential pieces. Without both, the costume does not identify as Mollie specifically.
Mollie is a real historical person, not a fictional character with quotable one-liners. In the film, her confrontation of Ernest is the most discussed moment. The line most people cite is: “You killed my people. You were supposed to love me.” It is not a party quote. It is the weight of the entire film in one sentence.
Recognition has faded since the 2023 release. The film was critically acclaimed but did not reach the broad audience of a mainstream blockbuster, and three years is enough time for most party crowds to have moved on. You will need to explain who you are at most events. That is not a dealbreaker, but go in knowing it.
You need most of them. The stacked necklaces and chokers together are what make the costume read as Mollie rather than generic 1920s period dress. Dropping one piece is fine. Dropping the stack entirely leaves you with a blouse and a skirt, which could be anyone.
If your hair is long and dark, braid it yourself and skip the extension. If your hair is short or light, the extension is the practical fix. Loose hair does not read as Mollie. The braid is the silhouette people see from behind, and it matters.
Martin Scorsese’s 2023 film is based on David Grann’s nonfiction book about the Osage Indian Murders in 1920s Oklahoma. The Osage Nation held oil rights that made them among the wealthiest people in the country. A coordinated campaign of murders followed, carried out by white settlers and their associates. Mollie Burkhart lost multiple family members before an early FBI investigation finally uncovered what had been happening. The film stars Lily Gladstone, Leonardo DiCaprio, and Robert De Niro.
