Throwing an epic visual event is a sure-fire way to get the #hashtags rolling in. We have put together 8 of the most unique party themes we’ve seen hosted at our party venue in Swindon. Or you can read our top 10 tips for making a good venue even better here.

1. Bright Lights

It’s time to bring out the retro glow in the dark stars, neon lights and brightly coloured clothing! This unique party theme is perfect for an evening event, feel like you’re partying under the stars or at a full moon party in Thailand with this glowing fun!

Creative adult party theme

By the time you are in your 20’s, it’s guaranteed that you have been to all the classic themed parties and in all honesty, they get boring. This is why neon lights and glow in the dark party themes are a fantastic and fun idea. Black lights, glow sticks, neon colours and face paint are what will make this event eye-catching and popular across Instagram.

Want to go all out? With this type of party you can even get glow in the dark treats that will leave a sweet taste in your mouth. Also excellent for Halloween parties for all ages! 

For the drinks, our top-secret tip that will be sure to impress… add tonic water to your beverages before exposing it to a black light!

2. Carnival & Circus

One of our favourite creative party themes for adults is a carnival or circus theme. This is definitely one that’s for those with a larger budget and does require good weather so you can hold it outside. 

For entertainment, hire jugglers, dancers & acrobats and your guests can relax, drink and enjoy a mind-bending show. This is definitely a great party theme for a milestone birthday to make it a day to remember! 

For the food? What’s a circus without popcorn and candy floss? These are great snack ideas to keep your guests satisfied throughout the night. You can also hire out a carnival and circus-themed photo booth for your guests to go wild in, full of accessories, hats & masks.

3. Botanical garden

Flower walls, greenery and tea cups (yes you can fill these with boozy cocktails) are what will make your Summer party fly off the wall and your guests have a good time! Aesthetics are becoming the most important factor of any bash and getting it right is important if you want to see your social profile getting tags and likes! A botanical garden party is a classy and unique party theme that will leave your guests dazzled.

If you want something a little more civilised then a botanical garden afternoon tea theme is a good idea to ensure you have a great time. You can choose to go totally Alice in Wonderland with an afternoon tea or keep it simple and pretty with the mix of greenery, flowers and candles – stunning in any photograph. For Summer events that will lead into the evening, decorate with cute fairy lights and bring out the champagne to create a magical feel as the sun starts to set. 

This is also a great ideas for kids birthday parties as you can create a fairy inspired afternoon tea with fairy lights, as well as mini sandwiches and cakes fit for a fairy princess!

4. Game & Cosplay

Ready player one? For this party idea, ask guests to come as their favourite video game character. There is plenty of themed decor that you can buy for this event, or alternatively make your own.

 Pinterest has a plethora of ideas for food, decorations, games and cosplay costumes party ideas. Once you have your Princess Peaches, Lara Crofts and Links, ensure to take a picture and use a #hashtag for Instagram to promote your event.

Fancy dress party theme

Cosplay is popular with so many people and makes a perfect party event. If you know your guests are passionate about gaming, then they will jump with joy at the opportunity to go all out as their favourite character – it’s the ultimate way to throw a totally geekish party! 

A great way to make sure your guests go all out is to make it a competition and get your guests dressed up! Let everyone vote on who they think has arrived in the best costume (and no, guests may not vote for themselves). Make sure the prize is a desirable one to ensure maximum effort.

5. Peaky Blinders

By order of the Peaky Blinders. We invite you to join Tommy, Arthur, Polly & Ada for a 1920’s gangster-themed party. Yes we know, this is probably not the most unique party theme around, however it is one of the most incredible party themes you can choose.

If you’re a Peaky Blinders fan, then I am 100% sure that you have spent time daydreaming about becoming part of the Shelby family. Lavish outfits, whiskey, gin, cigars, money and the ability to do whatever you want? AMAZING.

Outfit galore

If your guests go all out and your decor is on point then this will see the likes and comments rolling in. It’s also the perfect opportunity for a classic British roast dinner, with all the trimmings included. If it’s in your budget, then a timeless 1927 Bentley would be a fantastic backdrop for your photography pictures. #peakyblindersparty

6. Margarita Party

Tequila could be a theme, right? ! Any excuse for a Margarita! Roll out the red carpet for a cocktail evening inspired by your favourite drink.

Keep it classic with the original Margarita –  Tequila, sugar syrup, lime juice and a salted rim – or offer modern variants to tickle your guest’s tastebuds. 

We like the sound of frozen strawberry margaritas, coconut delights with a desiccated coconut rim and totally tangerine margaritas. We’ve hunted down all the best recipes here.

A Margarita is a popular Mexican drink so why not pair it with it some delicious Mexican food?

Burritos, chimichangas, tortilla chips and dips are what will make this unique party theme stand out from the rest.

7. Unicorn

Not everyone’s cup of tea, but the mix of beautiful pastel colours make for a charming Insta story. The unicorn theme was thrown into our pop culture in 2018 and we have yet to see the fad fade. From unicorn press on nails to Starbucks’ unicorn drinks and everything in between, it’s fair to say the trend has taken off pretty well. The Instagram hashtag for #unicorn has over 13 million posts, each containing its own weirdly wild and wonderful pastel themes.

One of the most prominent aspects of a unicorn themed party is of course the sickly treats! Donuts, cupcakes and popcorn are just a few of the must-haves for your event. Simply add some food colouring into your baking for magical treats. #unicornparty

8. Day of the Dead

The Day of the Dead is actually a colour exploding event to demonstrate love and respect for deceased family members. It is the extravagant face paints and colourful outfits that make this a fun party theme. 

Decor is the most important factor of a Day of the Dead party. Think flowers, sugar skulls and jaw-dropping costumes. What’s more, it’s such a widely known phenomenon that getting party decorations is easy peasy.

Something you should consider is hiring a professional face painter. I’m pretty certain that not everyone you invite to your party will have an artistic flair, yet people will want to look their best!
