Ambrose Spellman is Sabrina’s warlock cousin, a necromancer working in the family mortuary, and a man who once tried to blow up the Vatican in the late 19th century and has spent most of the time since under house arrest for it. The floral shirt and leather jacket combination, layered with a wine red scarf and stacked bracelets, builds the bohemian gothic aesthetic that defines his occasional departures from the mortuary. Chilling Adventures of Sabrina ran for four parts on Netflix and ended in 2020, so recognition at a general party depends on how many fans of the show are in the room.

  • 1 Cross Zip Leather Jacket (essential)The leather jacket is the structural anchor of this build. Ambrose wears velvet blazers and robes for his indoor look, but this leather jacket captures the same layered, textured quality in a more practically wearable form. Leave it open so the floral shirt underneath is visible at the chest. A jacket worn closed over the floral shirt collapses the layering effect and loses the bohemian intellectual read.

  • 2 Brown Black Floral Shirt (essential)The floral pattern is what makes the overall build read as Ambrose’s specific aesthetic rather than generic gothic. He favors rich, ornate fabrics with Victorian or botanical patterns under his robes throughout the show. Wear it buttoned but open at the collar, untucked. The shirt should be visible at the chest even when the jacket is on.

  • 3 Bead BraceletStack this on the same wrist as the leather bracelet. The layered bracelet combination is a specific detail of Ambrose’s accessory style, which runs toward antique and handmade rather than polished or commercial.

  • 4 Dark Blue JeansPlain dark denim, slim or straight fit. Check your wardrobe before buying. Any dark jean without prominent branding or distressing reads correctly here.

  • 5 Red FlaskA prop that adds character and gives you something to do with your hands at a party. Ambrose is a warlock who has been under house arrest for seventy-five years, and carrying a flask is entirely consistent with his coping strategies for that situation.

  • 6 Wine Red ScarfDraped loosely around the neck and allowed to fall asymmetrically. The wine red color references the deep burgundy and maroon tones of Ambrose’s signature indoor velvet robe, and ties the accessories back to his character palette without replicating the robe itself. Center-knot scarves read as a different aesthetic entirely.

  • 7 Leather BraceletWorn on the same wrist as the bead bracelet to create the layered effect. Any worn-in dark leather cuff works here. The stacking is what matters more than either piece individually.

  • 8 Brown SandalsAmbrose spends most of the show barefoot inside the mortuary. The sandals represent the rare occasions when he is allowed to leave. Any soft-soled leather sandal in brown or tan reads correctly. Check your wardrobe before buying.

How to Style the Ambrose Spellman Halloween Costume

The jacket needs to stay open. If it closes over the floral shirt the two-layer bohemian effect disappears and the costume reads as a generic leather jacket build. The floral shirt visible at the chest through the open jacket is what makes the combination specific to Ambrose’s aesthetic. The scarf should fall asymmetrically rather than hanging centered. Draped fabric centered over the chest reads as a costume accessory. Fallen to one side it reads as a personal style choice, which is the correct interpretation for this character.

Ambrose is the person Sabrina goes to when she has an idea that is either brilliant or catastrophically dangerous, and his job is to figure out which one it is before she has already started. He has been doing this for two seasons from inside a house. He also once tried to blow up the Vatican as a teenager and spent seventy-five years thinking about whether that was a good idea. The answer, based on available evidence, is that he still thinks it was, mostly.

Stack the bracelets before deciding which wrist they go on

The bead bracelet and leather bracelet together need to sit on the same wrist. Which wrist depends on whether you are carrying the flask in your dominant hand, since carrying props in the same hand as stacked bracelets means adjusting both every time you put something down. Decide at home before leaving and position both on the wrist that will be free more often during the night.

The scarf loses its shape over a long night indoors

A loosely draped scarf starts well and ends up bunched or shifted within two hours of arriving at an indoor event. Check the drape periodically before photos rather than at the end of the evening. If the fabric is thin and slippery it will migrate faster. A quick tuck at the back of the collar keeps the front fall in place without it reading as deliberately knotted.

Couples Idea

Ambrose Spellman & Prudence (Chilling Adventures of Sabrina)

Excellent pairing with genuine on-screen romantic and emotional history. Ambrose and Prudence develop one of the more compelling relationships in the series across Parts 2 and 3, and fans of the show will recognize the dynamic immediately. No dedicated CostumeRealm guide for Prudence yet, so that costume requires a scratch build using in-show reference. Her aesthetic runs to dark structured dresses and Victorian-influenced silhouettes, which contrasts well with Ambrose’s bohemian layered look.

Duo Idea

Ambrose Spellman & Nicholas Scratch (Chilling Adventures of Sabrina)

Strong warlock duo from the same show with a meaningful in-universe relationship. Nicholas Scratch is a student at the Academy of Unseen Arts and one of Sabrina’s central relationships in the series. The visual contrast between the two characters’ aesthetics reads clearly enough that fans of the show will place the pairing without additional context.

Group Idea: Chilling Adventures of Sabrina Cast

Ambrose Spellman, Nicholas Scratch, Sabrina Spellman, Prudence, Zelda Spellman

Strong group for a Sabrina watching crowd. The visual range across these five characters is broad enough that the group reads as a theme at a glance. Sabrina and Nicholas Scratch have CostumeRealm guides. Prudence and Zelda would need to be built from scratch, which requires commitment but produces a more complete group identity for the five together.

Group Idea: Iconic Pop Culture Magic Users

Ambrose Spellman, John Constantine, Willow Rosenberg, Dr. Strange

Might work, but these three source properties are far apart. John Constantine is a grimy supernatural investigator in a trenchcoat. Willow Rosenberg is a high school student turned witch from a 1997 TV show. Dr. Strange is a Marvel superhero in a sorcerer’s cloak. Ambrose is a Gothic bohemian warlock on house arrest. The shared theme of powerful magic users is real but the visual coherence across the four is low enough that the group concept needs explanation at most events.

Ambrose Spellman Halloween Costume DIY Tips

Building the Look

This is one of the more thrift-friendly builds in the Sabrina lineup. Most of these items exist in wardrobe or at second-hand stores. The floral shirt is worth searching for specifically, since the pattern is what makes the build character-specific. Everything else has a reasonable substitute.

  • Leather jacket: thrift this if possible. Any dark leather or faux-leather jacket with a clean silhouette works. The cross-zip detail is nice but not required if you find something close in style.
  • Floral shirt: worth hunting for specifically. Victorian or botanical prints in dark earthy tones are common at thrift stores. A plain shirt in a deep jewel tone is a lesser substitute but still works with the rest of the build.
  • Dark blue jeans: check your wardrobe first. Almost everyone owns these.
  • Brown sandals: very easy to thrift. Shape and color matter more than brand or condition.
  • Wine red scarf: any lightweight scarf in a deep wine, burgundy, or maroon tone works. Thrift stores almost always carry these.
  • Bead bracelet and leather bracelet: inexpensive new or easy to thrift. Stack both on the same wrist rather than splitting them.
  • Red flask: useful as a prop. Any flask works; the red color is a nice nod to the character palette but not essential to recognition.

Playing Ambrose at the Party

Ambrose is witty, unhurried, and slightly amused by most things that happen around him. He has been alive for over seventy-five years and spent most of them in a house. He does not rush. He also does not explain himself unless he sees a genuine benefit to doing so.

  • When asked who you are: “Ambrose Spellman. Warlock. Currently between assignments.” Do not elaborate on the house arrest unless someone already knows the show.
  • His best line for the party: “Witch law is the complete opposite. Guilty until proven innocent.” It applies to a surprising number of situations at a Halloween party.
  • Ambrose advises Sabrina constantly and is wrong less often than she is willing to admit. If someone in your group is playing Sabrina, this is the dynamic to maintain for the evening.
  • He is warm and genuinely caring toward the people he loves, which is what makes him interesting. Playing the full cynical detachment without the warmth underneath misses the character entirely.

Ambrose Spellman Halloween Costume: FAQ

Layer the Brown Black Floral Shirt under the Cross Zip Leather Jacket, pull on the Dark Blue Jeans and Brown Sandals, then drape the Wine Red Scarf loosely around the neck. Stack the Bead Bracelet and Leather Bracelet on the same wrist and carry the Red Flask. The floral shirt visible through the open jacket is the detail that makes the look specifically Ambrose’s bohemian warlock aesthetic.

Niche but recognizable within its crowd. Chilling Adventures of Sabrina ended in 2020 and is no longer in active release, so recognition at a general party depends on how many Sabrina fans are in the room. At a horror or dark fantasy themed event, the costume reads well and the bohemian gothic aesthetic is striking enough to carry itself even if people do not immediately place the character.

Two stand out. On the nature of witch justice: “Witch law is the complete opposite. Guilty until proven innocent.” And to Prudence about family: “Our desire for a father blinded us to the family we already have.” The second one hits differently when you know that Ambrose refused to name his accomplices after the Vatican incident, accepting seventy-five years of house arrest rather than betray people who were, by then, the closest thing to family he had.

Ambrose Spellman is portrayed by Chance Perdomo, who appeared across all four parts of the Netflix series (IMDb).

Ambrose was placed under a binding spell confining him to Spellman Mortuary after attempting to blow up the Vatican in the late 19th century, following a period when he had become a follower of Aleister Crowley. He was offered freedom in exchange for naming his accomplices and refused. He spent the next seventy-five years working as a mortician, coping with isolation through sarcasm, wit, and an increasingly refined indoor wardrobe.

Ambrose specializes in necromancy, the magic of death and communicating with spirits, which pairs usefully with running a family mortuary. He can also perform astral projection, teleportation, warding, weather control, and general spell casting. He is over seventy-five years old but appears to be in his twenties, which is a side effect of warlock longevity rather than particularly good skincare.

Yes. Ambrose is Sabrina’s cousin on the Spellman side. He lives with her, her aunts Zelda and Hilda, and the family cat Salem at Spellman Mortuary in Greendale. He functions as Sabrina’s primary magical research partner and the person most likely to tell her that whatever she is about to do will end badly, before helping her do it anyway.
