Decades Day Spirit Week Outfit Ideas (Every Decade)
The easiest decades day spirit week outfit ideas start with one key piece that screams the era, like a poodle-skirt shape for the 50s, flares for the 70s, a neon windbreaker for the 80s or a butterfly clip for the 2000s, and then you build the rest from your normal closet. One loud hero piece plus decade-appropriate hair beats a full costume every time.
If you already own great pieces but never know how to combine them, Your Era names which style problem is keeping you stuck and builds outfits from what you have. Find my era
Decades day spirit week outfit ideas: how to win
Decades day is a spirit week staple at a lot of US and Canadian high schools and middle schools. Sometimes it's "pick any decade," sometimes each grade gets assigned one (freshmen get the 50s, seniors get the 2000s, that sort of thing). In the UK, you're more likely to see this as a themed non-uniform day or a charity dress-down day, but the ideas are the same.
The winning formula:
- One key piece that instantly signals the decade
- Hair that matches (this does 50% of the work)
- Colors from the era
- Everything else from your closet in plain basics
Before you raid the costume shop:
- Check your parents' or grandparents' closets. Genuinely a gold mine.
- Thrift stores are perfect for this.
- Keep it school-appropriate and something you can sit through class in.
- Coordinate with your friend group for a group photo moment.
50s and 60s
50s outfit ideas
Key piece: a full skirt, or cuffed jeans with a white tee.
- Girls: full or pleated midi skirt, fitted cardigan buttoned up, scarf tied at the neck, ponytail with a ribbon, white sneakers or saddle-style shoes.
- Guys: cuffed straight jeans, plain white tee, a leather or denim jacket, slicked-back hair with gel. Very greaser.
- Last-minute version: white tee, cuffed jeans, hair ribbon or slick-back. Done.
60s outfit ideas
Key piece: a mini shift dress, bold mod print, or anything tie-dye for the late 60s.
- Mod look: black-and-white graphic top, short A-line skirt or straight trousers, heavy winged eyeliner if you like, knee socks.
- Hippie look (late 60s): tie-dye tee, flared jeans, headband across the forehead, peace sign necklace.
- Guys: turtleneck and slim trousers for mod, or tie-dye and a headband for hippie.
70s outfit ideas
Key piece: flares. Nothing says 70s faster.
- Disco: flared jeans or trousers, a satin or shiny shirt with a big collar, platform shoes, big curly hair.
- Boho: flared jeans, a peasant top or crochet vest, fringe bag, center-part hair.
- Guys: wide-collar shirt unbuttoned a bit, flared trousers, gold chain, center-parted hair or a pick in your afro.
- Colors: mustard, rust, brown, orange, avocado green.
Tip: wide-leg jeans you already own count as flares for decades day. Nobody's measuring.
80s outfit ideas
Key piece: neon, big shoulders or a windbreaker.
| 80s look | Pieces | Hair |
|---|---|---|
| Workout | Leotard or crop top over leggings, leg warmers, sweatband | Side ponytail, scrunchie |
| Neon | Neon tee, denim jacket, acid-wash jeans | Crimped or teased |
| Preppy | Polo with the collar popped, sweater tied around the shoulders, khakis | Neat side part |
| Rock | Band tee, leather jacket, ripped black jeans | Big and spiky |
| Windbreaker | Color-block windbreaker, track pants, high-tops | Anything, the jacket does it |
80s is probably the most fun decade to dress up for because it's supposed to be over the top.
90s and 2000s
90s outfit ideas
Key piece: a flannel, overalls, or a slip dress over a tee.
- Grunge: oversized flannel around your waist or unbuttoned, band tee, ripped jeans, combat boots.
- Clueless-inspired preppy: plaid mini skirt, matching blazer, knee socks.
- Hip hop: baggy jeans, oversized jersey or tee, bucket hat, sneakers.
- Guys: baggy jeans, flannel, backwards cap, chunky sneakers.
90s day spirit week tip: tons of people already dress 90s every day, so add one strong signal, like a choker, butterfly clips or a bandana, so it clearly reads "costume."
2000s / Y2K outfit ideas
Key piece: low-rise flare jeans, a velour tracksuit or a baby tee with a slogan.
- Y2K: baby tee, low-rise jeans, butterfly clips, tinted sunglasses, tons of lip gloss.
- Pop-punk: striped arm warmers, band tee, skinny jeans, studded belt, side-swept bangs.
- Guys: frosted-tip vibes (gel spikes), trucker hat, oversized graphic tee, cargo shorts.
2010s (yes, really)
It hurts, but the 2010s are officially a decade you can dress up as.
Key piece: skinny jeans or a galaxy print.
- Tumblr girl: skinny jeans, a skater skirt or band tee, flannel, Converse, flower crown.
- Early 2010s: chambray shirt, infinity scarf, riding boots, side bangs.
- Guys: skinny jeans, snapback, graphic tee with a mustache or galaxy print, high-top sneakers.
