Quick Answer: The Robin Arellano costume is a late-1970s teen look built around denim, a western belt, and a Virgin Mary pendant.
  • Black Wig (essential)
  • Virgin Mary Pendant (essential)
  • Vintage Denim Jeans
  • Customizable T-shirt
  • Cowboy Bandana
  • Western Belt

Robin is the toughest kid at Finney’s school, the one who fights bullies on his behalf and gets abducted for it before the film’s main story even starts. The costume itself is mostly period basics, so the pendant is what actually ties it to Robin specifically rather than any other 70s kid. The Black Phone was a sleeper hit in 2021 (Wikipedia) and got a sequel in 2025, which keeps Robin’s story in circulation even though he’s a supporting character.

  • 4 Cowboy BandanaWorn around the neck, it’s a small detail that reads as period-accurate without much effort. Easy to skip if you’re not going for full accuracy.

  • 5 Vintage Denim JeansStraight-leg, slightly faded denim sells the late-70s setting better than modern skinny or distressed styles. Check your closet before buying.

  • 6 Virgin Mary Pendant (essential)This is the detail that actually ties the costume to Robin specifically instead of just any 70s kid. It’s a small, quiet piece, so wear it where it’s visible, tucked into a shirt collar defeats the point.

How to Style the Robin Arellano Halloween Costume

The pendant is small, so it needs to sit outside the shirt collar where people can actually see it, not tucked away for safekeeping. The jeans and tee are doing the period work here, and going too clean or too new-looking undercuts the whole 70s setting. At a modern party under bright lighting, a costume that’s just denim and a t-shirt can read as “guy who didn’t dress up” rather than a specific character. The pendant and bandana are what earn this the status of costume instead of an outfit.

Robin starts a fight with a bully twice his size without blinking, then calmly wipes the blood off his knuckles in the bathroom like it’s nothing. If someone challenges you at the party, the move is total calm, not bravado.

Wear the pendant outside your shirt

A pendant tucked under fabric might as well not exist for the costume. Keep it visible on the chain, resting on top of the shirt.

Don’t over-style the wig

Robin’s hair looks a little messy and lived-in, not salon-fresh. If you’re wearing a wig, muss it slightly before you head out rather than leaving it stiff out of the packaging.

Duo Idea

Robin Arellano & The Grabber (The Black Phone)

Strong duo and the most obvious one from the film, victim and villain, instantly readable to anyone who’s seen it. The contrast between Robin’s plain denim and the Grabber’s mask does most of the work without needing an explanation.

Duo Idea

Robin Arellano & Finney Blake (The Black Phone)

Might work, but Finney doesn’t have a dedicated costume guide on this site yet, so this pairing is DIY on his half. It’s a genuine friendship from the film, just be ready to build his half from scratch rather than shopping a list.

Group Idea: The Black Phone Kids

Robin, Finney, Gwen (The Black Phone)

Strong group for anyone who wants the full sibling-and-friend dynamic from the film. Neither Finney nor Gwen has a costume guide here yet, so this group requires building two of the three looks yourself from reference photos.

Group Idea: Retro Horror Kids

Robin, Eleven, Mike Wheeler (crossover)

Might work, but this crosses The Black Phone’s late-70s setting with Stranger Things’ early-80s one, so the eras are close but not identical. It plays fine as a general “kids in a retro horror story” theme, less well if anyone at the party is picky about timelines.

Robin Arellano Halloween Costume DIY Tips

Building the Look

This is one of the cheaper builds on the site. Most of it is closet or thrift-store material.

  • Jeans and t-shirt: thrift stores are full of this stuff. Look for straight-leg denim, not modern skinny cuts.
  • Belt and bandana: cheap, easy to find, worth buying for the period detail.
  • Wig: skip it if your own hair already works. Check a mirror first.
  • Pendant: buy this one. It’s the single detail that makes the costume specific.

Playing Robin at the Party

Robin doesn’t posture before a fight. He just moves, then stays completely calm after.

  • When someone asks who you are: keep it short. “Robin. I look out for my friends.”
  • The line to use: “Someday you have to stand up for yourself.” Deliver it like older, hard-won advice, not a threat.
  • If a conversation gets tense, stay quiet and steady rather than escalating.
  • Don’t oversell the toughness. Robin’s confidence is calm, not loud.

Robin Arellano Halloween Costume: FAQ

Vintage denim jeans, a graphic tee, and a western belt build the late-70s base. Add the cowboy bandana, the black wig if your hair doesn’t already fit, and the Virgin Mary pendant, and the look is complete.

The Black Phone was a sleeper hit in 2021 and got a sequel in 2025, so the film is fresh in people’s minds. Robin is a supporting character though, not the lead, so recognition depends on the crowd actually having seen it rather than just knowing the title.

“You’re gonna have to stand up for yourself one of these days.” Also, from beyond the grave: “I don’t want to die for nothing. I want to at least have died for a friend.”

Miguel Cazarez Mora plays Robin in the 2021 film (IMDb), directed by Scott Derrickson and based on Joe Hill’s short story of the same name.

Robin is abducted and killed by the Grabber before the main events of the film. His ghost later contacts Finney through the basement’s disconnected phone and teaches him how to fight back.
