80s Throwback

This fun theme can spark great costume and décor ideas and give you an excuse to rock out to old hits from Prince, Bon Jovi, Guns N’ Roses, Cyndi Lauper, Michael Jackson and many more artists. Guests can dress up as their favorite musician or celebrity from the 80s or simply in colorful 80s attire. Don’t forget the big hair, bold make-up and neon colors!


Who doesn’t want to feel like a superhero for a day? Your guests can choose to dress up as their favorite superhero (or villain) and you can serve snacks with superhero insignias and colors. You can decorate the venue with Avengers themes or the theme of any other superhero. Our DIY superhero balloon garland kit (pictured below) is perfect for this theme! This idea is awesome for kids (and even adult Marvel fans)!

Game of Thrones

Game of Thrones may have ended but that doesn’t mean that you can’t throw a Game of Thrones themed party and delve back into Westeros! Since Game of Thrones is one of the most-watched shows of all time with some fabulous costumes, it makes for the perfect party theme for teenagers or adults. Whether you want to dress up as a proud Brother of the Night’s Watch or as the Mother of Dragons herself, you can be sure that you’ll have a fun party. As for food, you can create some memorable medieval dishes and sip on some ale or wine from fancy goblets.

Tropical party

A tropical theme is always a fun party theme, especially in the summer. It’s also a great excuse to listen to some Caribbean beats, dance and sip on piña coladas. You can also decor your house with fun colorful balloons and other decorations.

Music Festival

Hosting a mini music festival for your next party allows you the option to play a variety of fantastic songs, dress in carefree music festival attire and perhaps even host an open mic for your guests to show off their musical talents. This type of party requires little decorations besides finding an outdoor space and setting up a small stage with music and DJ equipment.

Burning Man

This theme is similar to the music festival theme but it has its own little twists. Your guests can get creative and come up with wild costumes complete with feathers, lots of jewellery wigs and more.

1001 Arabian Night

Bring the stories from the Arabian Nights to life with opulent décor, vivid colours and beautiful costumes. Bright pillows, feathers and gold are a must for this theme.

Murder Mystery

Murder Mystery parties and dinners and super fun and allow guests to create great memories together. You’ll usually want a murder mystery kit or game for this party that’ll provide you with different plot lines and settings. Guests get to play a character solving a mystery. In order to help the guests prepare and for them to know how to dress, it can be useful to send them invites with an introduction to their character before the party. You can also serve dishes and drinks related to the time and place of the murder mystery.

Roaring 20s Great Gatsby

The 20s were a wonderful time for lavish parties and fashionable clothes. Why not throw a party that’ll make Mr. Gatsby himself jealous? Have your guests dress up, sip on some gin and play some jazz (or even the soundtrack from The Great Gatsby movie) and dance the night away! Some great colours for your 20s themed party decor include black and gold. You can create a 20s vibe by using a balloon arch garland with those colors. This theme also works for any kind of party be it a birthday party, New Year’s Eve Party, Wedding or Halloween.

Underwater Theme

This is a cool creative choice for kid’s birthday parties, especially for kids who are fans of mermaids or sea life. Decorations can include blue ocean-themed colors and pictures and balloons with sea life. Guests can either dress as mermaids or sea animals.

Wonderland Theme

This is another great theme party idea for kids. You can organize activities around the storyline from Alice and Wonderland and have guests dress up as their favorite characters from the story. Of course, do not forget the fancy tea cups! Our DIY pink and rose gold balloon garland kit is oh! so perfect for this theme, with its soft and delicate colors!

Glow in the Dark Party

This is a fun idea for kids and adults alike. You can place glowing stickers all over the walls and ask your guests to wear white so their clothes will glow in the dark as well. You can even take the theme further by placing stickers of stars and planets around the walls to give a planetarium experience.


Circus or Carnival Party

Have kids dress up as magicians and circus or carnival casts. You can even bring in a real magician to wow the kids with some magic tricks. Wow your guests at your circus or carnival party with our DIY rainbow balloon garland kit.
