Our Top 21st Birthday Party Ideas

 

The Roaring Twenties

Unleash your inner Gatsby with a roaring twenties-themed party. Guests can dress to the nines in their finest flapper dresses and sophisticated suits, whilst sipping on a tasty Tom Collins or classic Negroni. You can set the scene with classy decor such as vintage cigar boxes and gold photo frames adorned with pearl necklaces. Hire a swing band to help transport your guests back to the jazz age, and make sure there’s a dance floor available for guests to party the night away.

Vegas Casino Night

Why not bring the glitz and glamour of a Vegas casino to life for your son or daughter’s 21st birthday party? You can easily transform any venue into a luxury casino with the addition of blackjack and poker tables manned by professional card dealers. Mood lighting and cocktails are a must, and you could even create a bespoke themed menu to match the games. Ask your guests to dress in their classiest casino attire and supply plenty of poker chips as decor.

Masquerade Ball

Add an element of sophistication to your luxury 21st birthday celebration with a masquerade ball theme. Encourage your guests to wear elegant evening gowns and sharp suits, with elaborate masks to create a sense of mystery. A masquerade ball should have plenty of opportunities for lavish banquets, dancing and drinking. Kensington Palaces is the ideal venue for a masquerade ball, boasting glorious gardens and banquet tables for your luxury 21st soiree.

Rosé & Roses

If your offspring loves all things pink, this could be the perfect theme for their 21st birthday party. Transform your garden space with gorgeous greenery and plenty of roses, whether they be natural or artificial arrangements. Serve up some pink punch or signature botanical cocktails with traditional garden games for guests to enjoy. A traditional sit-down meal or more informal buffet option could work well with this theme – you could even design a rose-infused menu! You can discover more luxury party food ideas in our blog.

Black & White

Set the scene for an impressive insta-worthy 21st affair with a classy black and white theme. This dress code is easy for guests to follow, and you can get away with simpler decor choices. Hire a bartender to create some signature monochromatic cocktails and choose an elegant black and white birthday cake. You could always include some fun pops of colour to highlight certain features of the venue, for example a red carpet or gold glitter photo booth.

Around the World in 80 Days

If your son or daughter has always wanted to go travelling, an exotic around-the-world adventure theme could be the perfect fit. Separate your venue into distinctive areas that represent different continents, countries, or cities. Include themed food, drink and decor within each area to help set the scene. Consider hiring a fun photo booth with themed travel props to create a truly unforgettable experience.

Midsummer Night’s Dream

There’s nothing quite like an enchanted garden party to celebrate turning 21. Transform your outdoor space into an enchanted wonderland topped with twinkling fairy lights and lush floral arrangements. Encourage guests to dress as their favourite fairytale characters and play fun garden games such as croquet or giant jenga. Our team of luxury event planners recently organised a fabulous fairy tale party for 250 guests at a private garden in South Gloucestershire. It truly was a night to remember!

Popular Decades

Relive the journey to becoming 21 by throwing it back to distinctive decades. Choose music, food, and drinks that represent that era to create a memorable and nostalgic experience. For example, if your son or daughter was born in the 2000s, you could celebrate with a fun pop party theme. Hire a DJ to play some throwback pop tunes and ask guests to dress up in neon costumes with glittery makeup to fit the theme. Our recent 21st birthday bash in London featured a fantastic set from the Soul Jets – one of the grooviest decade bands around.
