A Great Gatsby party is one of the easiest themes to pull off well. Almost everyone has a picture in their head of the Roaring Twenties: beaded dresses, feathered headbands, pinstripe suits, jazz on the record player and a coupe of something bubbly. That shared picture means guests know what to wear without a long explanation, and you can focus on creating an atmosphere. Whether you are planning a milestone birthday, an end-of-year work function, a Christmas cocktail evening or a New Year's Eve gathering, this guide walks through the whole plan, from invitations to the playlist, with plenty of ideas for 1920s flapper costumes and dapper menswear along the way.
Why a Gatsby Theme Works So Well for Cocktail Parties
F. Scott Fitzgerald's 1925 novel describes Jay Gatsby's parties as lavish, glittering affairs on Long Island, and that image has stuck. A cocktail party is the perfect scale for the theme: it is elegant without being exhausting, and the focus stays on conversation, drinks and a bit of dancing. Because the dress code is so recognisable, guests tend to make an effort, which instantly lifts the room.
The theme also suits a wide range of ages and budgets. A guest can go all out with a full sequinned flapper dress and matching headpiece, or simply add a string of pearls and a feather band to a little black dress. Men can wear a full three-piece suit or keep it simple with braces, a bow tie and a flat cap. Everyone ends up looking like they belong in the same photo, which is exactly what you want.
For a cocktail format, a guest list of roughly 12 to 30 people works well in a home or a small function room. Fewer guests feel intimate and relaxed; more than that and you will want a bigger space, a bar helper and a proper dance floor.
Step 1: Send Gatsby-Style Invitations Early
Send invitations three to four weeks ahead, especially in November and December when calendars fill quickly. That gives guests time to plan and order their outfits rather than scrambling the week before. Art deco design is easy to recreate: black or navy backgrounds, gold geometric borders and a classic serif font set the tone straight away.
Spell out the dress code clearly. Phrases like "Roaring Twenties attire", "Gatsby glamour" or "1920s black tie" all work. It also helps to include a line of inspiration for guests who are unsure where to start, for example a link to a range of flapper dresses or a reminder that a fedora and braces are enough for the men. Digital invitations are perfectly fine, and they make it easy to send a reminder a week before the date.
Step 2: Plan the Outfits for Women and Men
For women, the flapper dress is the centrepiece. Look for a dropped waist, a straight silhouette and plenty of movement from fringing, beading or sequins. Hemlines in the era sat around the knee, so a knee-length dress feels authentic while still being comfortable to dance in. Black, gold, silver, champagne and deep jewel tones such as emerald and burgundy all photograph beautifully under party lighting. Guests who want a fuller fit can browse plus size flapper costumes, which keep the same dropped-waist look in a more generous cut.
For men, the classic Gatsby look is a well-fitted suit, ideally with a waistcoat, paired with a crisp shirt and either a bow tie or a slim tie. Pinstripes lean towards the gangster side of the decade, while a plain light suit nods to Gatsby himself on a summer evening. A men's 1920s gangster costume is a quick, reliable option if a guest does not own a suit, and braces, a pocket square and spats over the shoes add the finishing detail.
Step 3: Finish the Look with 1920s Accessories
Accessories are what turn a nice dress or suit into a convincing Gatsby outfit. For women, the essentials are a headband or headpiece (feathered, beaded or jewelled), a long string of pearls, long gloves and a beaded clutch. A faux cigarette holder makes a fun photo prop. Hair can be pinned into a faux bob with finger waves at the front, and makeup is all about a defined lip in a deep red or berry shade.
For men, a fedora or flat cap, a bow tie, braces and a pocket watch chain are the key pieces. Two-tone shoes or spats over black shoes complete the outfit. A wide range of these pieces can be found among our 1920s accessories, which makes it easy to build an outfit from clothes already in the wardrobe. If you are hosting, consider keeping a small basket of spare headbands, bow ties and strings of pearls by the door so any guest who arrives underdressed can join in.
Step 4: Serve Prohibition-Era Cocktails and Finger Food
The 1920s in America were the Prohibition years, when alcohol was officially banned and speakeasies flourished behind unmarked doors. Gatsby's fortune was rumoured to come from bootlegging, which gives you a great story to play with. Set up a "speakeasy" corner with a password on the door, or label the bar "Gatsby's Private Reserve".
Classic drinks of the era are simple to make in batches: the French 75 (gin, lemon, sugar and sparkling wine), the Bee's Knees (gin, honey and lemon), the Sidecar (brandy, orange liqueur and lemon) and a plain glass of bubbles served in a wide coupe. Include a non-alcoholic option, such as sparkling lemonade with a twist of citrus, so every guest has something elegant to hold.
For food, keep it bite-sized and easy to eat with one hand: devilled eggs, oysters, smoked salmon blinis, mini sandwiches with the crusts removed, cheese straws and a tower of small cakes. Silver trays and paper doilies do a lot of the styling work for you.
Step 5: Decorate in Art Deco Style
Art deco is defined by bold geometry, symmetry and metallic finishes, so stick to a palette of black, white and gold with touches of silver. Gold balloons, feather centrepieces in tall vases, strings of faux pearls draped over the table and candles in glass holders create a glamorous look quickly. Stack coupe glasses into a pyramid for a champagne tower moment, or simply cluster them on a mirrored tray.
Lighting matters more than any single decoration. Turn off harsh overhead lights and use lamps, fairy lights and candles instead. Set up a photo backdrop with a gold fringe curtain or a black sheet with a simple deco frame, and leave a few props nearby. Guests love a photo wall, and it gives you a record of everyone's outfits at the end of the night.
Step 6: Music, Dancing and Party Games
Jazz and swing set the mood immediately. Search a streaming service for 1920s jazz, Charleston or electro swing playlists; electro swing blends vintage horns with modern beats and tends to get people dancing later in the evening. If you have a record player, a few second-hand jazz records add a lovely authentic touch.
A short Charleston lesson is a great icebreaker. Pull up a beginner tutorial on a screen, gather everyone for five minutes and then let the dancing take over. Other easy activities include a "best dressed" award for the most convincing flapper and the sharpest gent, a murder mystery game set in a 1920s mansion, or a simple card table for a bit of mock casino fun. Keep games light and optional so guests who just want to chat and sip cocktails can do exactly that.

Frequently Asked Questions
What should I wear to a Great Gatsby themed party?
Women usually wear a dropped-waist flapper dress with fringing or sequins, a feathered or jewelled headband, pearls and T-bar heels. Men wear a suit or waistcoat with a bow tie, braces and a fedora or flat cap. Metallic tones, black and jewel colours all fit the theme.
Is a Gatsby party suitable for a Christmas or New Year's Eve event?
Yes. The glamour, sparkle and cocktail focus suit end-of-year celebrations perfectly, and a black and gold colour scheme works for both. It is also a popular theme for work Christmas parties because it is easy for every guest to join in.
What is the difference between a Gatsby outfit and a gangster outfit?
Both come from the 1920s. A Gatsby look is about polished glamour, often a lighter suit or classic black tie. A gangster look leans darker, with pinstripes, a fedora, braces and sometimes a toy prop. Either is perfect for a Roaring Twenties party.
How far in advance should I send invitations?
Three to four weeks is ideal, and closer to five weeks during the busy November and December party season. This gives guests enough time to order an outfit and plan accessories.
What drinks were popular in the 1920s?
Gin-based cocktails were very popular during Prohibition, including the Bee's Knees and the French 75, along with the Sidecar and sparkling wine served in coupe glasses. Offer a non-alcoholic sparkling option as well.
Can men wear accessories only instead of a full costume?
Absolutely. A white shirt and dark trousers with braces, a bow tie and a fedora reads clearly as 1920s. Adding a waistcoat or a pocket watch chain takes it a step further without needing a full suit.
