Costume Advice

LONG ARM OF THE LOL ROLES

Badges, Bluffs and Busted Alibi costume guide.  These characters keep law and order—or at least pretend to. Whether badge-wearing professionals or delusional vigilantes, they come with sharp instincts, sharper sunglasses, and a dramatic sense of justice. Some play it straight. Others… abuse the siren.

LAW ENFORCER LOOKS

TYPES OF MURDER MYSTERY PARTY CHARACTERS

Police Officer (Beat Cop, Patrol, or Rookie)

By the book... unless they lost the book.
Costume: Navy shirt, badge, utility belt, aviators.
Behavior: Hands always on hips. Calls everyone “ma’am” or “perp.” Loves saying “That checks out.”

Detective (Hard-Boiled or Glam Noir)

Solves crimes and drinks coffee like it’s a sport.
Costume: Trench coat, fedora or messy bun, dress shirt with tie or scarf.
Behavior: Constant note-taking, suspicious squinting, monologues no one asked for.

Sheriff or Deputy (Classic or Small-Town)

Owns the town—or thinks they do.
Costume: Cowboy hat, khaki uniform, shiny badge.
Behavior: Southern drawl optional. Says “Not in my town” a lot. Enjoys pointing dramatically.

FBI / Federal Agent

Mysterious, overqualified, and always scanning the room.
Costume: Black suit, white shirt, earpiece, sunglasses indoors.
Behavior: Talks in acronyms. Refuses to confirm or deny anything. Might say, “This is bigger than you think.”

Judge (Stern or Dramatically Biased)

Wields a gavel and personal vendettas.
Costume: Black robe, powdered wig or reading glasses, lace collar if you’re feeling RBG.
Behavior: Bangs gavel over petty disputes. Declares people “Out of Order!” and objects to everything, even snacks.

Bounty Hunter (Rough & Ready or Overdramatic)

Has one job: bring someone in. Doesn’t really know who.
Costume: Tactical vest, gloves, aviators, maybe a bandana or leather coat.
Behavior: Constantly checks a crumpled wanted poster. Says “You match the description.” Growls unnecessarily.

Security Guard (Rent-a-Cop or Overachiever)

Loves the vest, takes the job way too seriously.
Costume: Polo or button-up with a patch or name tag, walkie-talkie.
Behavior: Constantly checking “zones.” Has a whistle and uses it. Carries a clipboard of “infractions.”

Undercover Officer (Obvious or Surprisingly Good)

Too cool—or too obvious—to blend in.
Costume: Hoodie over badge, jeans, sunglasses at night.
Behavior: Keeps whispering into sleeve. Drops hints like, “I’m not who you think I am.”

Vigilante / Self-Appointed Justice-Seeker

Didn’t ask for permission. Probably carries zip ties.
Costume: All black, hoodie, dramatic mask or bandana.
Behavior: Intense eye contact. Talks about “the system” being broken. Has a fake code name like “Night Falcon.”

Corrupt Cop

Knows the rules—just doesn’t follow them.
Costume: Standard uniform... but make it messy. Loose tie, shades, money peeking from pocket.
Behavior: Winks too much. Says things like “Everyone has a price.” Always on a mysterious phone call.

Park Ranger (Suspiciously Invested in Trail Crime)

Protects forests... and overreaches wildly.
Costume: Ranger hat, green shirt, cargo pants, binoculars.
Behavior: Talks in nature metaphors. Says “This picnic reeks of foul play.” Arrests someone for “disturbing the squirrels.”

Police K-9 Handler (With or Without Dog)

Talks to their imaginary partner. “He doesn’t like you.”
Costume: Tactical pants, vest, leash with no dog.
Behavior: Describes the dog's reactions constantly. “Sniffed your shoe. You’re hiding something.”

Character Behavior Tips:

  • Voice & Diction:

    • Serious tone, even for dumb things: “We’ve got a situation by the snack table.”

    • Sudden whispering into a shoulder mic

    • Shout “Freeze!” for no reason, then apologize awkwardly

    • Bark commands. Use legal jargon wrong on purpose.

    • Introduce yourself with full title: “Deputy Supreme Justice Ranger Quinn, Lawman-at-Large.”

  • Mannerisms:

    • Check everyone’s ID (real or fake)

    • Talk like you're always mid-investigation

    • Refer to guests as “persons of interest” 

    • Flash badge over minor issues (e.g., someone cutting in buffet line).

    • Keep making “notes” no one sees.

    • Dramatically whisper “I’m watching you” then walk away slowly.

  • Catchphrases:

    • “I’ve got my eye on you.”

    • “Something doesn’t add up...”

    • “Ma’am, I’m gonna need to see your alibi.” 

    • “This is an active investigation.”

    • “We’ve got a code cupcake.”

    • “You’re not under arrest… yet.”

    • “Justice doesn’t sleep—but I did nap earlier.”

Whether you’re corrupt, clueless, or competent, the Law Enforcer role gives you license to interrogate, overreact, and dramatically “secure the perimeter” (aka, the snack table). Grab a badge, raise an eyebrow, and get ready to lay down the law—even if you’re wildly unqualified to do so.
