Types Of Mermaid Themes

The great thing about a mermaid party theme is that there are so many different ones to choose from. You’re spoilt for choice when it comes to planning this beautiful theme. Here are some of the more popular mermaid party themes for you to choose from. Instead of just heading straight to Kmart, we help you work out the best mermaid theme and where to get the best decorations!

Pastel Mermaid Theme

There’s something about the dreamy pastel colours that really bring the magic to a mermaid party. Opt for the laid back colours that simply blend into each other to create the amazing under the sea look. Purples, pinks, yellows, blues… you have plenty of choice when it comes to colours, just keep them nice and soft and use your imagination with the theme. A simple balloon garland can really bring this look together.

Under The Sea

A mermaid party doesn’t need to be solely focused on mermaids. Part of their magic comes from under the sea, so it can help to incorporate this into your theme. There are so many amazing, mystical creatures that can live under the sea with our mermaid friends. Show off the seaweed, clam shells, coral, starfish, seahorse and more.

Gold and Mint Mermaid party

Picking two colours that go well together, such as gold and mint, is the perfect way to create a mermaid party. You can use the colours as the base of your theme, adding in a few mermaid touches to complete the look, and you have the perfect party ready to go.

Little Mermaid Party

Of course, let’s not forget the famous movie: The Little Mermaid. It’s enough to inspire any little girl’s party and make her dreams come true. You can use characters from the show to help with the set up and really bring the movie to life. It’s the perfect mermaid party theme!

If you’re pulling together a party, here are some extra tips to help you out when shopping for those all-important party supplies:

  1. Pick a theme first:

    You want to narrow it down from a simple ‘mermaid party’ to the exact type of party you’re planning to throw. Choose the colours and the look and feel of the party right at the beginning, as this is what will help you when it comes time for shopping the look.

  2. Look for inspiration:

    Have a look on our site, or do a simple Google and get as much inspiration as possible for your party planning. This will help you work out what party supplies you actually need and how you plan on pulling everything together. It’s much easier to work from a vision you can see, rather than from one in your head.

  3. Work with your space:

    Whether you’re having an indoor party at home, or inviting everyone up to the local park, it’s important to be mindful of the space you’re using. See if you can find parties that used a similar space to give you some inspiration when it comes to the set up.

  4. Shop in advance:

    Sourcing products from overseas can save you plenty of money, but the downside is that they can take a while to arrive. If you have the space, shop ahead of time and store all your party decorations in the one handy place in your home ready for the big day.

  5. Take lots of photos.

    We are often so busy running around on the big day that photos get forgotten. Once the set up is done, go ahead and take plenty of photos before the kids even arrive. Once the kids are there, go and ask another adult to be on dedicated photo-taking duties. That way, it won’t get forgotten.

  6. Have fun!

    Don’t let the stress of the day get to you. After all, birthday parties are all about fun. Does it really matter if the streamers fall? Of course not! Does it really matter if your balloon garland isn’t perfect? No! What really matters is that the birthday child has plenty of fun on their big day.

Good luck pulling together your mermaid party. We can’t wait to see the results! If you’re keen to share with us, please email [email protected]
