10 Unforgettable 21st Birthday Party Themes

If you were born in 1999, it’s your time to shine! It’s no secret that turning 21 is a big deal, so why not celebrate in style at one of Brisbane’s top 21st birthday party venues?

But first things first – let’s talk themes to set the scene. If there’s one thing that we all know at The Fox Hotel, no 21st birthday party in Brisbane is complete without a styled function room to get everyone in the party mood. To help you with the party planning process, we’ve put together a great list of 21st birthday party themes to ensure your celebration is unforgettable.


The early 2000s is ripe with memorable (and some forgettable) trends. Pink was dropping one hit after another; tube tops were appropriate for almost any occasion; and belts were almost as wide as scarves. Capture the nostalgia of the 2000s with a themed birthday bringing back all those loved, hated and secretly-loved styles.

Our customisable function space, The Canvas Room is perfect for committing 100 percent to your theme. Adorn the white walls with posters of hunks and babes from the 2000s (J.Lo, Britney Spears and any of the boys from N Sync or the Backstreet Boys), then let us take care of the music, drinks and any 2000s-inspired party games you can think of.


Bring the colour, music, revelry and free-spirited nature of festivals to your 21st birthday in Brisbane. Pick your favourite festival or bring in elements of Coachella, Lollapalooza, Splendour in the Grass, Bluesfest and Burning Man. There’s no limit to the creative dress-ups this theme affords, from rainbow fanny packs and eye glitter to bucket hats and knee-high socks.

The Rooftop is the ideal venue for a festival-themed party, lending its funky décor, cocktail bar, and urban views to the overall atmosphere. It can host up to 360 guests, giving you plenty of space to set up specific areas for different festivals or to create the festival of your dreams, without the inflated drink prices.


The preppy/country club theme adds just the right amount of fancy and casual to a 21st birthday party. We’re thinking chinos, blazers and polos for the guys and sundresses, skirts and tasteful blouses for the ladies.

It works perfectly with Queensland’s sunny climate, best enjoyed upstairs on The Rooftop. We can also see you celebrating in true preppy style in The Veranda Room, which matches the theme with wicker furniture, vibrant wallpaper and a plantation home feel.

Function Rooms & Event Venues in Brisbane


Celebrating your 21st birthday in Brisbane is the perfect time to tap into your fancy side with a black-tie soiree. The women will look absolutely stunning in their gowns and jewellery, while the men can channel their inner James Bond with debonair black suits and ties.

Our French-inspired 21st birthday venue, The Boudoir, is perfect for a small affair with designer furnishings and expertly crafted cocktails. Alternatively, party under the fairy lights in The Canvas Room or enjoy the exclusivity of a private bar surrounded by exposed-brick walls in The Atrium.

The letter theme

Remember when we all learned the alphabet for the first time? Well, now it’s a 21st birthday party theme! Yep, we’re referring to ‘Munching Mike’ and ‘Annie Apple’! 

To make this theme a thing, get everyone to dress up as something starting with the first letter of your name (because, it’s your birthday?), or even their own name! It’s guaranteed to produce some hilarious results, so get those creative juices flowing and watch your party kick into overdrive – unless your name begins with X…then perhaps the following theme ideas might be more your jam.

Masquerade Ball

There’s nothing quite as glamorous or mysterious as a Masquerade party, and for your 21st birthday…it’s absolutely perfect. Often referred to as ‘the ultimate party’, a Masquerade gives guests the freedom to move about the party as they please, all while being surrounded by class and luxury. 

Think art-deco style decorations in The Canvas Room, as well as feathers, drapes, candelabras, chandeliers and so much more. The possibilities with this 21st birthday party theme are endless, so add it to your party planning list, stat. 

All White Party

Forget your LBD, make your 21st a white theme for the ultimate 21st birthday statement. Yes, sister we are entering serious Beyonce and Solange territory! Nothing says suave better than everyone dressed in white, and a room filled with white balloons, divine table settings, and plenty of mood lighting. But, for the sake of your all-white-getup, maybe hold the red wine…

1920’s inspired-Gatsby Party 

It’s been done many times before, but that doesn’t make it any less fun, and now we’re in the year 2020, we reckon there’s no better occasion to party like Gatsby than your 21st birthday. 

Pay homage to the grand party era of the 1920’s with feathered headbands, sequinned dresses, strands of pearls, old school suiting for the guys, and a mix of jazz and ragtime music. You can’t get more Gatsby than that.

Mad Hatters Tea Party

If you have an affinity for the weird and wacky, then treat your guests to a mystical, mind-blowing Alice in Wonderland Mad Hatters Tea Party. 

Mix and match furniture of all shapes and sizes, have white roses painted in red on the table, odd-shaped dishes and cups, quirky cocktails and unique canapés. You can opt for a dark and twisted version in The Canvas Room, or stick to bright, fun colours in the Atrium.

Double Denim

For something more laid black, don your double denim and hit the dance floor in complete comfort. Who knew Britney and Justin would start the party trend of a lifetime!

Or in a similar fashion, you can opt for a 90’s theme party when double denim, white sneakers and speed sunnies were a hit. It’s fun, easy and automatically lightens the mood of any party.
