When Did People Start Dressing Up For Halloween

Okay, so grab your coffee (or tea, I don’t judge) and let’s talk about something deeply important: Halloween costumes. When did we all decide that October 31st was the perfect night to dress like a sexy lobster or a inflatable T-Rex?

I mean, it feels ancient, right? Like, surely cavemen were doing it. But the truth is way weirder—and way more fun—than you’d think.

Let’s start with the Celts. Like, 2,000 years ago. They had this festival called Samhain (pronounced “sow-in,” which sounds like a fancy pig).

The idea? The boundary between our world and the spirit world got all blurry. Ghosts could walk right through your front door. No big deal, right?

So, the Celts got smart. They built huge bonfires and wore animal skins and heads. Seriously. Deer heads. Cow skins.

Why? To trick the ghosts. If you looked like a scary spirit, the other spirits would think you were one of them. “Oh, that’s just Steve the Bear-Spirit. Carry on.” It was the world’s first Halloween costume: a ghost-proof disguise.

Fast forward to the Middle Ages. The Church got involved (as they do). They smooshed Samhain with All Saints’ Day and All Souls’ Day. Now it was a Christian-ish holiday called Halloween.

And here’s where it gets charming. Poor people would go door-to-door on Hallowmas (Nov 1st) and beg for food in exchange for prayers. It was called “souling.” They’d wear simple masks or blacken their faces.

But the real costume shift came in Scotland and Ireland in the 1800s. Young folks started “guising” (short for “disguising”). They’d dress up in white sheets or old rags, carry a turnip lantern, and perform a little poem or song for a treat.

Halloween Costumes That Disguised, Spooked and Thrilled Through the

These weren’t sexy cats. These were ghosts and goblins. Scary stuff. The goal was still to blend in with the supernatural. Or at least to scare your neighbor enough to get a piece of cake.

Then, the Irish potato famine happened. Millions of Irish and Scottish immigrants flooded into America. And they brought their Halloween traditions with them. Yay for us!

In America, things got… commercial, fast. By the late 1800s, department stores in the U.S. started selling mass-produced Halloween costumes. Think: creepy masks, paper witch hats, and skeleton suits.

These early store-bought costumes were still spooky. They leaned hard into ghosts, devils, and black cats. The whole “sexy nurse” trend was still a century away. Thank goodness.

The 1950s is the real turning point, though. Post-war, everyone had a little more cash. And, more importantly, TV happened. Suddenly, kids didn’t just want to be a ghost—they wanted to be Superman or Mickey Mouse.

Companies like Ben Cooper and Collegeville started pumping out those iconic boxed costumes with the thin plastic mask and the smock that ripped after one wear. You remember those. They smelled like a chemistry lab.

Pop culture took over. Halloween costumes stopped being about warding off spirits. They became about pretending to be your hero for one night. And, let’s be honest, getting candy.

By the 1970s and 80s, adults wanted in on the fun. Sexy costumes exploded. Why be a scary witch when you could be a “Sexy Witch”? Why be a plain cat when you could be a “Sexy Cat”?

The humor got big, too. In the 90s and 2000s, we got pop culture parody costumes. Remember when everyone dressed as Britney Spears? Or the “sexy” version of a mailman? (I still don’t know who asked for that.)

Now? It’s a free-for-all. You can be a meme, a viral TikTok filter, or even your own WiFi router if you’re feeling meta. The only rule is: there are no rules.

So, when did people start dressing up? Technically, 2,000 years ago with the Celts in animal skins. But the why shifted from “survival” to “self-expression” to “I’m going to win the costume contest at this bar.”

Honestly, I think both are valid. Whether you’re wearing a deer head to confuse a ghost or a inflatable unicorn to confuse your coworkers, you’re part of a very old tradition. And that’s kind of beautiful.

So this Halloween, when you’re struggling with that plastic mask’s terrible elastic string, just remember: you’re carrying on a 2,000-year-old party. And ghosts definitely approve of the sexy pizza slice costume.
