If you’re planning a bachelorette party, you need to read this list of 16 unhinged bachelorette themes with group costume ideas. Why? Because basic is boring. Your bride deserves a send-off that’s unforgettable (and let’s be real- slightly unhinged is where the best memories happen).
I’ve planned a fair share of bachelorette weekends, from beach getaways to city chaos, and hands-down the most fun themes are the ones where everyone goes all-in with the costumes. Nothing bonds a group of friends faster than showing up at the club dressed like the founding fathers or a bunch of “dads” in tube socks and fanny packs.
Ready for a party that will have everyone laughing, snapping pics, and making core memories? Here are 16 of my favorite unhinged bachelorette themes, plus group costume ideas that’ll make your crew the hit of the night.
1. Their Love is Locked Up 🖤
Theme: Orange is the new bridal white.
Group costume idea: Everyone dresses like prisoners or mugshots.
This one was a hit at my friends Vegas bachelorette. We got cheap orange jumpsuits from Amazon and ironed on fake prison numbers with her wedding date. We even made little mugshot signs on sticks for our photos.
Pro tip: Print out everyone’s “crime” for their mugshot sign, “stealing hearts,” “shoplifting champagne,” “public intoxication,” etc.
And the bride? She wore a sparkly white jumpsuit and carried plastic handcuffs. By the end of the night, people were begging to take photos with us.
Bonus ideas:
- Temporary tattoos
- Mugshot backdrop for the Airbnb photoshoot
- Playlist with “Locked Up” and “Jailhouse Rock” vibes
- Bar signs: “Hard Time, Good Times” and “Cell Block Sangria”
2. Last Night of Independence 🇺🇸
Theme: Revolutionary party energy.
Group costume idea: Founding fathers, Uncle Sam, or colonial chic.
This is perfect for a 4th of July bachelorette weekend, or for any bride who loves a good theme. Think powdered wigs, waistcoats, colonial dresses, Lady Liberty, Uncle Sam hats, and American flag everything.
I saw this theme go viral and lost it when one girl showed up in full George Washington regalia, wooden teeth and all. The bride was in a sparkly uncle sam costume. It was hilarious and totally over-the-top in the best way.
Fun extras:
- Red, white, and blue jello shots
- Founding Fathers trivia night
- Choreographed “Hamilton” number after a few rounds of drinks
Decor ideas:
- Red, white & blue balloon arch
- Declaration of Independence table sign
- Founding Father’s punch bowl (spiked tea!)
- Mini sparklers for photo ops
3. Till Death Do Them Part 🧟♀️
Theme: A love that can survive the apocalypse.
Group costume idea: Dress like zombies.
Zombie bachelorette? Absolutely. This is great for an October wedding and can go full Halloween mode. Everyone wears ripped clothes, smears on gray makeup, and add some fake blood. Do a “zombie march” down the street to dinner. The bride can wear a white dress (thrifted!) and look like a zombie bride.
Tips:
- Do a pre-party makeup session so everyone looks coordinated
- Add white contact lenses if you’re feeling brave
- Host a zombie walk TikTok dance-off
Decor ideas:
- Black and red roses
- Skull centerpieces
- “Bloody” cocktails
- Flickering candlelight everywhere
4. We Give Our Blessing 👔
Theme: Ultimate dad vibes.
Group costume idea: Dress like dads.
Think: New Balance sneakers, cargo shorts, Hawaiian shirts, socks with sandals, beer belly pillows.
This theme has been everywhere lately, and for good reason. It’s cheap, it’s comfy, and it’s absolutely hilarious. You can even host a “dad joke off” at the pregame.
Ideas:
- Bring grilling props, fishing rods, or golf clubs for pics
- Play a drinking game where you have to talk with dad sayings (“Back in my day…” “Let’s check the thermostat…”) Or get the Dad Joke Button
- Harry belly Fanny Packs
Decor ideas:
- Grilling photo booth backdrop
- Lawn flamingos + Dad’s Garage sign
- Display snacks or charcuterie in tackle boxes
- Beer can tower centerpiece
5. Brides Last Hair-rah 💇♀️
Theme: Wigs, wigs, and more wigs.
Group costume idea: Do a funny wig exchange.
This one is low effort but high impact. Everyone brings the wackiest wig they can find. At the start of the night, you draw names and swap wigs.
We did this for my friend bachelorette in Ashville and ended up with a group photo of mullets, pastel bobs, rainbow hair, and one George Washington wig. The bride? She rocked a giant blonde beehive. We combined it with our wine tasting day and it was definitely the highlight of the trip.
Pro tip: Bring wig caps and bobby pins so they stay on while you dance.
Decor ideas:
- “Wig out” neon sign
- Wig styling station with hairspray, clips
- Sparkly tinsel curtain photo booth
- Glitter disco ball baloons
6. RIP to Her Last Name ⚰️ Or ‘Till Death Do Us Party’
Group costume idea: Dramatically mourn in black while the bride wears all white.
This is one of my favorite unhinged bachelorette themes with group costume ideas, and it’s SO Instagrammable.
Everyone wears funeral-chic black outfits: veils, gloves, black lace, sunglasses, dramatic makeup. The bride is the “ghost” of her single self in a stunning white outfit.
One group I saw even rented a fake coffin for photos. Over the top? Yes. Iconic? Also yes.
Ideas:
- Print funeral programs with funny “eulogy” about her last name
- Do a slow, somber procession into the first bar and pass out tissues as props
Decor ideas:
- Black roses & candles
- Coffin blackboard sign to display the drink menu
- Fake gravestone props
- Black lace table runners
7. “Until They’re Old and Gray” 👵 OR… “My Neck, My Bach”
Theme: Grannies gone wild.
Group costume idea: Dress like old ladies.
This one is so fun and easy.
Rollers in the hair, floral housecoats, orthotic shoes, giant costume jewelry. If you can find a walker with tennis balls on the legs- perfection. Just pop into a goodwill and you will be set.
We drank champagne out of tea cups and danced the night away.
Extras:
- Play bingo while you pregame
- “Early bird special” dinner at 5 PM
- Do a group chair yoga session
Decor ideas:
- Doilies on tables
- Tea party tableware
- “Golden Girls” marathon on the TV
8. Lets Get the Government Involved in Her Relationship 🗳️
Theme: Political party, literally.
Group costume idea: Dress up like your favorite politicians. A pantsuit party? Yes, please
If your bride loves political satire (or just enjoys making a statement), this theme is a winner. Everyone picks a politician or political stereotype, from campaign managers to conspiracy theorists, secret service, interns… and the one that forgets a costume can be a swing state voter.
Tips:
- Make silly campaign buttons (“Vote for the Bride!”)
- Do a mock debate during pregame over which bar to go to

- Someone needs a briefcase
Decor ideas:

9. She Finally Found Him 🎯
Theme: Where’s Waldo but make it bridal.
Group costume idea: Dress in red and white stripes; the bride dresses as Waldo.
This is cute for a bar crawl or scavenger hunt night. Everyone wears red and white striped shirts or dresses, and the bride is decked out as Waldo, hat, glasses, striped shirt, the whole deal.
We did this in Austin, and people at every bar were trying to “find Waldo” in the crowd. Perfect for silly group pics too.
Extras:
- Plan an actual scavenger hunt around the city
- Hand out little prizes for whoever “finds” the bride first at each bar
- Bonus points for giving the MOH a referee whistle
Decor ideas:
- “Where’s the Bride?” sign
- Striped tablecloths

10. ‘That Ring Tho’ 🥊💍 or ‘The Perfect Match’
Theme: Knockout bride vibes.
Group costume idea: Dress up as boxers; bonus, host a funny boxing tournament.
If your bride loves a sporty theme or group activities, this one’s a knockout (literally). Everyone dresses in boxing shorts, robes, sports bras, and gloves.
The bride can wear gold boxing shorts, a sparkly robe, and a championship belt that said “Bride to Be.”
Tips:
- Play “Eye of the Tiger” and “We Are the Champions” all night
- Give everyone mouthguards (even just for photos!)
Decor ideas:

11. Same Pinot Forever 🍷
Theme: Wine & cheese party, and dress for your fave wine region.

We did this for a chill Sunday afternoon. Each guest brought wine from their “region” and paired it with cheese. Bride wore a white flowy vineyard-inspired dress.
Decor ideas:
- Grapevine garlands
- Wine tasting scorecards
- String lights + rustic table settings
- use a DIY Wine Tasting Party kit
12. Last Romp in the Swamp 🫏
Theme: Shrek-core bachelorette.

13. BRIDE’S HEREEEE! AHH YEAHH GETTING MARRIED YEAHH 🎉 Or ‘Wheres the Bach’
Theme: Jersey Shore bachelorette bash.
Group costume idea: Snooki, Pauly D, The Situation, big hair, leopard print, bedazzled everything, a megaphone.
I saw this done for a bachlorette in Atlantic City and it was next-level. Bride wore a “We have a Situation” tank top. Group was full Jersey Shore chaos.
Decor ideas:
14. Marie Antoinette Bachelorette 🎂👑
Theme: Opulent, over-the-top French royalty, “Let Them Eat Cake!”
Group costume idea: Think corsets, tall powdered wigs, lavish gowns, pearls, fans, and lace gloves.
I love this theme, its so extra and so fun. Rent or DIY Marie Antoinette-inspired looks. The bride can wear a huge white tulle skirt and corset with a sky-high wig and tiny crown. Sip champagne, eat macarons, and take the most iconic Rococo era photos.
Decor ideas:
- Gold accents & pastel color palette (blush, mint, lavender)
- Tiered cake as the centerpiece

ok I lied, theres two more themes:
15. ‘Bride, Where Have You Been Loca? ‘ OR ‘This Is the Skin of a Bride, Bella‘ 🧛♀️🐺
Theme: Twilight-core bachelorette, because the saga lives on forever.
Group costume idea: Body glitter, Cullen clan, werewolves, and someone must be Charlie Swan.
I saw this theme and as a diehard twilight fan I loved it. The bride was sparkly Vampire Bella in a white corset dress + body glitter. They had a cutout of Edward in a suit, dressed up as a whole wolf pack in denim and cut-offs, Alice in a pixie wig, and one brave soul showed up as Charlie with a fake mustache and a mug of coffee.
Everyone had body glitter. Obvi.
Decor ideas:

- Twilight quotes as signage (“You’re intoxicated by my very presence” On theme? yes.)
- Photo booth with a Forks forest banner

16. Future Real Housewife 💎🍾
Theme: Real Housewives takeover, glam, drama, and taglines galore.
Group costume idea: Dress as your favorite Real Housewives star or just go full Bravo wife energy, sparkly cocktail dresses, over-the-top glam, big hair, designer bags, and giant statement jewelry.
We did this for my sister’s bachelorette and it was so iconic. The bride wore a sash that said “Future Real Housewife” and carried a champagne bottle like a clutch. Everyone else came as their fave housewife, we had Lisa Vanderpump, Teresa flipping a table, and of course Bethenny Frankel with a skinnygirl margarita.
The key here? COMMIT to the persona. Lots of staged arguments, dramatic wine sipping, and yelling “I’ll tell ya how I’m doin’, not well bitch!” in public.
Decor ideas:
- “Future Real Housewife” banner and sash
- Tagline making station, everyone writes their own personal tagline
- Giant champagne tower
- Glitter tablecloths + who is hunky dory napkins
