Quick Answer: Lady Gaga’s Harley Quinn from Joker: Folie a Deux is eight pieces, all built around the diamond argyle pattern.
  • Red structured blazer worn open (essential)
  • Diamond pattern tights (essential)
  • Diamond argyle sweater vest underneath the blazer
  • Black mini leather skirt
  • Black ankle boots
  • Black handbag
  • Red lipstick with crisp edges
  • Winged black eyeliner, upper and lower

Lee Quinzel spends Joker: Folie a Deux convincing Arthur Fleck to stay the Joker, and when he finally rejects the persona, she leaves. The film is on IMDb if you need a refresher. The red blazer is the piece that makes this costume work at a party. Without it, the diamond tights and sweater vest could be anyone. With it, the silhouette is immediately specific to this version of Harley. This version of the character is unusual in that Harley is the dominant one in the relationship, not Joker. That is worth knowing before you try to play her at a party.

  • 1 Red Structured BlazerThe essential item. Worn open throughout the film so the sweater underneath stays visible. A structured blazer with defined shoulders holds the silhouette. An unstructured jersey blazer collapses and loses the shape that makes this version of the character recognizable.

  • 2 Diamond Argyle Sweater VestWorn under the open blazer so the diamond chest panel stays on show. The argyle pattern here is the same motif that reappears on the tights. That repetition is what ties the whole costume together as a deliberate look rather than a random combination.

  • 3 Black Mini Leather SkirtKeeps the lower half clean and simple. The tights do the visual work below the hem; the skirt just needs to stay out of the way. Check your wardrobe first.
    See on Amazon
  • 4 Black HandbagCarried throughout the film’s courtroom and public scenes. It is a small but specific detail that places the costume in the real-world wardrobe register Gaga’s Harley occupies, rather than the comic book version.
    See on Amazon
  • 5 Diamond Pattern TightsThe second essential item. The argyle motif on the tights mirrors the sweater above and makes the diamond pattern a deliberate visual system rather than a coincidence. Order these in advance; they are harder to find locally than everything else on this list.
    See on Amazon
  • 6 Red LipstickBold and precise. Use a lip liner first to get a clean edge; smeared red lipstick reads as a different Halloween character entirely. The lip needs to be vivid enough to match the blazer from across a room.
    See on Amazon
  • 7 Black EyelinerApplied to both upper and lower lids with a slight wing at the outer corner. The liner and the red lip together are the two makeup elements that most place this costume in the film’s specific aesthetic register.
    See on Amazon
  • 8 Black Ankle BootsCheck your wardrobe first. Any clean black ankle boot works. They just need to be clean and low enough that the tights remain the visual focus at the bottom of the outfit.

How to Style the Lady Gaga Harley Quinn Halloween Costume

The blazer is what people notice first, and it must be worn open. A buttoned blazer hides the sweater and removes the only thing that makes this specifically Gaga’s Harley rather than a woman in a red blazer. The costume fails at a party the moment the blazer closes. The diamond pattern underneath disappears, and so does the character. The specific failure to watch for is pairing the wrong shade of red: a blazer that is too dark or too orange against the black-and-white tights stops reading as a deliberate color choice and starts looking like a mismatched outfit.

In the film, Lee Quinzel attends Joker’s trial every day, dressed for an audience, and delivers her support to him with absolute composure whether she is lying or telling the truth. When he eventually rejects the Joker persona and tries to offer her something real, she tells him he killed the fantasy and leaves. The costume is exactly that: a performance outfit worn by someone who only exists in the performance.

Use a lip liner before the lipstick

Vivid red lipstick without a liner migrates into the fine lines around the mouth within an hour of a party, especially with a drink in hand. Liner first, then lipstick, then a light dusting of translucent powder over the top. A smeared red lip reads as a zombie or a clown, not as this version of Harley. The precision is specifically what distinguishes this makeup from every other Halloween red lip.

No pigtails, no white face paint, no exceptions

Both of these details belong to the animated Harley Quinn or the Birds of Prey version. Adding either one immediately shifts the reference away from the Gaga film and toward a different character entirely. If someone hands you pigtail holders at a party and says it would look better, they are wrong and you should decline.

Lady Gaga Harley Quinn Group Halloween Costume Ideas

Same Film Couple

Harley Quinn and The Joker (2019)

Strong pairing, and the visual contrast does the work without explanation. Gaga’s polished red-and-diamond Harley next to Joaquin Phoenix’s Arthur Fleck in a worn red suit and smeared clown makeup reads immediately as the film’s central dynamic to anyone who has seen it. The color echo of both wearing red while looking completely different is also a useful visual accident that makes the couple read as intentional from a distance.

Harley Quinn Joker (2019)

Gotham Villain Duo

Harley Quinn and Catwoman

Conditional pairing. Catwoman and Harley Quinn do not share a film or a specific moment, so the group only works as a “Gotham villains” concept rather than a specific reference. That said, red-and-diamond against all-black leather is a clean visual contrast, and both characters are recognized without needing the other to explain the group concept. Works best at events where people are happy with the general DC villain frame rather than a specific film.

Harley Quinn Catwoman

Two Harley Quinns

Lady Gaga Harley and Birds of Prey Harley

Conditional duo that requires both people to know both films well enough to explain the concept. The visual contrast between Gaga’s tailored red blazer look and Margot Robbie’s colorful maximalist version is genuine and striking, but most people at a general party will just see two Harley Quinns rather than a deliberate comparison. Works best at events where the crowd is already invested in DC and will get the meta-reference without prompting.

Lady Gaga Harley Birds of Prey Harley

Gotham Villains Group

Harley Quinn, Joker, Catwoman and The Riddler

Strong four-person group with no visual overlap between any costume. Each character has a distinct color: red for Harley, red-and-white chaos for Joker, all-black for Catwoman, green-and-purple for the Riddler. The group reads as a unit from across a room without needing explanation, and the range of aesthetics means no two costumes compete for attention. The only practical challenge is four people committing, which is always harder than it sounds.

Lady Gaga Harley Quinn Halloween Costume DIY Tips

What to Buy and What You Might Already Own

  • Diamond tights: buy these early, harder to find locally than everything else
  • Diamond argyle sweater vest: widely available, thrift stores often have argyle
  • Black leather skirt: check your wardrobe first
  • Black ankle boots: almost certainly already owned
  • Black handbag: check your wardrobe
  • Red lipstick and black eyeliner: under $15 combined from any pharmacy

Playing Lee Quinzel at the Party

Lee Quinzel is composed, certain, and completely committed to a fantasy that the other person has already stepped out of. The character does not perform. She just believes. The composure is the character.

  • “We’re gonna build a mountain,” delivered flatly, to anyone, as a statement of fact
  • Do not explain the costume if someone does not recognize it; just maintain eye contact and smile slightly
  • Lee is the dominant one in her relationship with Joker. She is not the sidekick in this film, and playing the costume as though she is changes everything about the character
  • If someone asks who you are dressed as: “Lee.” Not Harley, not Harley Quinn. She is never called Harley aloud in the film

Lady Gaga Harley Quinn Halloween Costume: FAQ

Eight pieces: red structured blazer worn open, diamond argyle sweater vest underneath, black mini leather skirt, diamond pattern tights, black ankle boots, black handbag, red lipstick, and winged black eyeliner. The red blazer and diamond tights are the two essential items. Without both, the costume reads as a general red blazer outfit rather than this specific Harley Quinn.

  • “We’re gonna build a mountain.” (Her recurring declaration about what she and the Joker will do together)

Most of Lee’s other lines in the film are about keeping Arthur committed to the Joker persona. When he finally rejects it, she tells him he killed the fantasy and leaves. For in-character delivery, “We’re gonna build a mountain” said with complete composure and no irony is the line. Note that she is never called “Harley” aloud in the film. She goes by Lee.

Yes, though the film released in 2024 so it is slightly less current than it was. The look is distinctive enough that DC fans and anyone who saw the film will place it, and the costume is wearable enough that it holds up even if someone misses the specific reference. It is one of the few Harley Quinn versions where the outfit could pass as intentional fashion rather than a Halloween costume.

A structured red blazer worn open over a black-and-white diamond argyle sweater vest, a black mini leather skirt, diamond-pattern tights, black ankle boots, and a black handbag. Her makeup is bold red lips with sharp black eyeliner on a pale matte base. Her hair is blonde and loosely styled. No pigtails, no white face paint.

No pigtails, no jester hat, no white face paint, and no specialist costume pieces. This version is built from real wardrobe items. Unlike most versions of the character, this Harley is the dominant figure in the relationship while Joker is the meek one. She is also never called Harley in the film. She goes by Lee.

Yes. The argyle diamond pattern appearing on both the sweater and the tights is what makes this a deliberate look rather than a random combination. Without the tights, the costume is a red blazer and a skirt. Order them in advance as they are harder to find locally than the other pieces.

Joaquin Phoenix’s Arthur Fleck Joker is the natural pairing: worn red suit, white face paint, smeared clown makeup. The contrast between Gaga’s polished Harley and Joker’s dishevelment communicates the film’s dynamic without any explanation needed. Catwoman also works as a Gotham-villain pairing that does not require a partner to wear clown makeup all night.
