These ideas run from flapper dresses and dapper suits to a champagne tower, a live acoustic band, and a speakeasy stage, and how much room and how many hours the space gives you decides which ones fit.
A rented house with dim corners handles a gold fringe doorway curtain, a photo backdrop, and one signature cocktail with custom signage.
A hotel ballroom has the space for a speakeasy stage and dance floor, plus a live vintage acoustic band. Prohibition ran 13 years, so I would pick the pieces that make a room feel like a speakeasy before adding anything else.
1. Flapper Dresses and Dapper Suits
Prohibition ran 13 years, and the clothes of that stretch are what guests are really dressing for.
Skip the hunt for exact period pieces. A sequined dress in a straight, dropped-waist cut and a dark suit with a fedora already read as 1920s in a crowd, so you can stop there if time is short.
I would pick one anchor per guest: a headband or long beads for her, a tie or hat for him. Put that in the invitation, so nobody shows up in a costume-shop bag.
2. Art Deco Metallic Decor with Feathers
Black and gold carry this table, and pearls plus black feathers keep it from looking flat. Before buying, decide how many place settings you need, since gold cutlery and Art Deco plates add up fast.
Check that the champagne coupes match the number of guests. A numbered table card is a small touch I like, because it also works as a seating guide.
3. Classy Finger Food and Elegant Appetizers
Serving food in small glasses and paper cones means guests can hold a drink in the other hand. Dip in a martini glass with toast, layered cups with spoons, and charcuterie cones all share that logic.
Decide which dishes can be filled ahead of time, since cups and cones can be lined up before anyone arrives. If anything needs to stay warm, plan for a heat lamp and a counter near an outlet.
4. 1920s Murder Mystery Game
A murder mystery gives guests something to do besides stand with a drink.
Count your guests before choosing a game, because a boxed mystery is written for a set number of players.
5. Create a Champagne Tower
A champagne tower is mostly about the base.
Test the stack before the party, since coupes are shallow and wobble easily. Florals, fabric drapes, and a cluster of small candles behind it make it look like a centerpiece rather than a glassware pile.
6. Live Vintage Acoustic Band
An accordion, an acoustic guitar, and a double bass make a sound that fits a speakeasy better than any playlist.
Ask about volume and space before booking.
A three-piece band needs room for a double bass, and a dim, warm room helps the mood. Live music costs more than a playlist, so confirm the fee and set length first.
7. Speakeasy Stage and Dance Floor
Red velvet curtains behind a gold marquee frame give the stage its drama, and the black and gold checkered floor tells guests where to dance. Metallic palm trees on each side add height.
Measure your room before copying it.
The stage and the floor both need space, and guests still need a path to the bar. Decide where the marquee lights plug in, too, since they need an outlet within reach.
I would pick the checkered floor over a bare one, because it marks the dance area without a word.
8. Gold Metallic Fringe Doorway Curtain
A gold metallic fringe curtain over a doorway turns the entrance into a small reveal: guests push through the shimmer and land in the dining room, candles lit.
Measure the doorway frame before ordering so the fringe hangs the full height. Decide what hangs behind it, because candlelight and a set table are what make the gold read as glamorous rather than as a party-store prop.
Hang it last, once the room behind it is finished.
9. Themed Cocktails with Custom Signage
Purple cocktails with rosemary sprigs look styled before anyone has taken a sip, and a sign reading "Have a ROARING GOOD TIME" tells guests what the station is for.
Settle on one signature drink instead of a long menu; matching glasses keep it tidy. Pearls and a wooden crate give the table height, so set the glasses at different levels on a white tablecloth.
I would have the sign lettered in Art Deco style, since that one detail ties the drinks to the era.
10. Gangster and Speakeasy Photo Backdrop
Wanted posters, a mobster silhouette cutout, money bags, and faux gold bars make a backdrop that tells a story, and a gold shimmer wall keeps it bright for photos.
Pick one wall with room for guests to stand in front, then build outward from the posters. Black and gold balloons fill the corners, and wooden crates give you a place to stack props at different heights.
I like a made-up name on the posters, like "Uncle Abe’s Moonshine," because guests read it and laugh before they pose.
Advice on Venue Selection
Prohibition is the story behind this party, so pick a venue that fits it: a rented house or event space with dim corners, or a hotel ballroom if you want chandeliers.
Either can pass for a speakeasy once the lighting is low.
Black, deep green, and gold make a tight palette that photographs well and keeps the room from looking cluttered.
Green and gold also nod to money, which suits an era built on new fortunes, so I would put those two up front.
Empty liquor bottles, old labels, and small wooden boxes set a speakeasy mood cheaply, and I would scatter them rather than line them up.
For a hidden-stash look, hang bottles from twine looped over the rim of a tub, then let them sit in ice so guests have to pull them up.
Wooden crates work for serving the rest of the drinks, and they also give you a few extra inches of height on the table.
Before booking, ask the host whether you can bring in your own decorations and hang things.
Tips for Music Selection
Jazz is the music to pick, and I would build the playlist around it. Build the playlist yourself or borrow a ready-made one, but check it for flow before the night so there are no dead stretches.
The 1920s also had its own dances, and the Charleston is the one I would teach. It is simple enough that a room of beginners can follow it, and it gets guests moving together instead of watching from the edge.
Pick a moment early in the evening for a short lesson, while people are still fresh.
Skip the full costume-shop version of the era; it reads as a joke more than a party. A few strong statement pieces, a good cocktail menu, and the right playlist will carry the night without much else.
Costume Planning Tips
Put the dress request in the invitation, and send it early. People need time to plan, and a room where most guests are in costume feels like a different event.
Gatsby-era dress covers a wide range, from casual to dressy, so guests have room to choose. Name some options: flappers, socialites, dapper gents, and bootleggers give people a place to start.
I would word the request as an invitation rather than a rule. Guests who feel pushed into a costume tend to arrive in the cheapest one.
A reminder a week or so before the party helps the stragglers.
Frequently Asked Questions
What do you wear to a 1920s party?
For her, a straight, dropped-waist dress covered in sequins does the job; for him, a dark suit and a fedora. I would add one anchor item per guest: a headband or long beads, or a tie or hat.
What are some theme ideas for a Gatsby-themed party?
Start with a black, deep green, and gold palette, then build a speakeasy feel with a fringe doorway curtain, a champagne tower, and a gangster photo backdrop.
Add live jazz or a jazz playlist and a short Charleston lesson early in the evening.
What were the roaring 20s called?
The Roaring Twenties is the name for the decade of the 1920s, also called the Jazz Age.
People remember the decade for its money and its excess: flappers, gangsters, jazz clubs, and the sharp geometry of Art Deco. Prohibition began in 1920, so a speakeasy theme fits the decade well.
What are some fun and creative ideas for a 20th birthday party?
A Roaring 20s theme suits a 20th birthday, since the music, dancing, and dress-up keep guests busy all night.
Dancing the Charleston, a murder mystery game, and a photo backdrop with made-up wanted posters keep people busy beyond standing with a drink.
