You’re standing in the middle of a Spirit Halloween or scrolling through some endless Etsy shop, and it hits you. Every single aisle is basically just a rift in time. Specifically, it’s a rift between the fuzzy, feathered, polyester-heavy 1970s and the neon-soaked, Lycra-stretching madness of the 1980s.
These two decades own the costume market. Seriously.
But here’s the thing: most people get it totally wrong. They mix up the eras or, worse, they wear some "generic disco guy" outfit that looks more like a shiny trash bag than anything John Travolta actually touched. If you want to nail 70 and 80 costumes, you have to understand the fabric, the cultural "why," and the specific subcultures that defined these years. It wasn't just "vintage." It was a total overhaul of how humans dressed to express themselves.
The Disco Fallacy and What the 70s Actually Looked Like
When people think of the 70s, they immediately jump to Saturday Night Fever. White suits. Big collars. But that was only a tiny sliver of the decade's DNA.
The early 70s were basically the 60s with a hangover. It was "Earth Mother" vibes. We’re talking about 70 and 80 costumes that prioritize crochet, heavy denim, and muted tones like mustard yellow, burnt orange, and avocado green. If you aren't wearing something that looks like it could double as your grandmother’s living room rug, are you even doing the 70s?
Halston changed everything. Roy Halston Frowick—the man was a legend—brought in the ultrasuede and the draped jersey dresses. If you want a "classy" 70s look, you look at Studio 54 photos of Bianca Jagger. You don't buy a cheap polyester jumpsuit with gold sequins. You look for draped fabrics that move when you walk.
Then there’s the hair.
The Farrah Fawcett flip isn't just a hairstyle; it's a structural engineering feat. If your wig doesn't require a gallon of hairspray to stay away from your face, it’s not authentic. For the guys, it’s the sideburns. Thick, bushy, slightly unkempt sideburns.
Why the 80s Feel Louder (But Are Actually More Complex)
The transition into the 80s wasn't a slow fade. It was a car crash of color.
By 1982, the fitness craze took over. Jane Fonda happened. Suddenly, 70 and 80 costumes started including leg warmers, spandex, and headbands for no reason other than "looking active." But honestly, the 80s were deeply divided. You had the Preppy look—think The Breakfast Club or Pretty in Pink. You had the Goth/New Wave scene with The Cure and Siouxsie and the Banshees. And you had the Power Dressing era.
Shoulder pads.
If you can fit through a standard doorway without turning sideways, your 80s shoulder pads aren't big enough. This was the era of Dynasty and Dallas. It was about looking rich, looking sharp, and looking like you owned a multi-billion dollar oil company even if you were just going to a house party in the suburbs.
Avoiding the "Costume in a Bag" Trap
Here is a pro tip: stop buying the pre-packaged bags.

Those "80s Pop Star" kits are usually just a neon tutu and some fishnet gloves that fall apart before you finish your first drink. They look cheap because they are cheap. If you want to stand out, you hit the thrift stores.
Real 80s vintage is heavy. The denim is thick. The leather jackets—think Thriller era Michael Jackson or Top Gun—have a weight to them that modern fast fashion can't replicate. When you search for 70 and 80 costumes, look for specific pieces. A real members-only jacket. A genuine Diane von Furstenberg wrap dress (or a good vintage knockoff).
The difference is in the texture.
The 70s were tactile: corduroy, velvet, suede. The 80s were synthetic: lace, leather, Lycra, and silk. Mixing these up is the fastest way to look like you're wearing a "generic old person" outfit.
The Music Connection
You can’t talk about these costumes without talking about the charts.
In the 70s, you’ve got the Glam Rock movement. David Bowie’s Ziggy Stardust. That’s a masterclass in costume design. It’s not just "aliens." It’s Japanese avant-garde mixed with kabuki theater. If you’re going for Glam Rock, you need platforms. Not just boots—huge, chunky, 4-inch soles that make you walk like a newborn giraffe.
Fast forward to the 80s, and you have the MTV effect.
Suddenly, everyone knew exactly what Cyndi Lauper was wearing every second of the day. Layers. That was the secret to 80s fashion. Layers of necklaces, layers of skirts, layers of belts. It wasn't about one "look"; it was about wearing everything you owned at the same time and making it look intentional.
Making It Work in 2026
Modern parties are different. We have high-definition cameras on our phones. A bad wig stands out a mile away.
If you're planning a 70s look, focus on the silhouette. High-waisted trousers with a flare that starts at the knee, not the thigh. It elongates the leg. It looks cool even if you aren't at a costume party.
For the 80s, it’s all about the "more is more" philosophy, but with a bit of modern grooming. You don't necessarily need the blue eyeshadow up to your eyebrows (unless that's the vibe), but you definitely need the bold lip.
And please, for the love of all things holy, watch the fabrics.
Cheap polyester from a bag will make you sweat. You'll be miserable within twenty minutes. Look for cotton blends or actual vintage pieces. Your skin will thank you, and you’ll look like someone who actually lived through the era rather than someone who just googled it five minutes before leaving the house.
Actionable Steps for Your Next Look
- Pick a specific year, not a decade. 1971 looks nothing like 1979. 1981 is basically the 70s with skinnier ties, while 1989 is the birth of grunge and neon. Pick a year and look at the Sears catalog or Vogue archives from that specific month.
- Focus on the shoes. Shoes are the foundation of any 70 and 80 costumes effort. Platforms or clogs for the 70s; Reebok high-tops or pointed-toe pumps for the 80s. If the shoes are wrong, the whole outfit is a lie.
- Master the "Big Hair" technique. For the 80s, you need to crimp and tease. For the 70s, it’s all about the blow-dry and the center part. Use modern products—volumizing mists are better than the sticky resins they used back then.
- Hunt for hardware. Don't just wear a shirt. Find the right belt buckles, the right aviator glasses, or the right chunky plastic earrings. The 80s were the golden age of "junk jewelry."
- Check the fit. 70s clothes were often tailored very tight through the torso. 80s clothes were oversized and boxy. Buying a size up for an 80s look or tailoring a 70s shirt can make a $10 thrift find look like a $500 wardrobe piece.
