8 Magical Ideas for the Ultimate Mermaid Party

Mermaids are one of the biggest party themes of the summer. Here’s how to host the best mermaid party ever by transforming your space into a magical iridescent underwater world.

Following the release of the successful The Little Mermaid movie featuring Halle Bailey in the summer of 2023, the figure of the mermaid remains a favoured party go-to for kids. Indeed, here at Meri Meri, the mermaid is one of our most popular party themes. And no wonder – there’s something mystical and otherworldly about the beautiful sea maidens.

A themed party gives you the opportunity to indulge in some underwater-themed creativity, and we've come up with several ways to create the best mermaid birthday party. Enjoy!

How to create a mesmerizing mermaid party table?

‘Choose a tablecloth that represents the sea, in blues or greens. Sprinkle sequins onto the tabletop to give some sparkle. Use glass vases as fish tank centerpieces. Place pebbles and shell beach finds in the bottom, cut out thin fish from carrots peelings and use kale and broccoli as seaweed or buy several of the mermaid birthday cards and have them running through the table as a central decoration.’

How to bring extra drama to the mermaid theme?

‘Stick fringed mermaid garlands and shell plates to walls to set the scene, and there could even be a separate decorated area for photos and tattoos, with mermaid costumes, crowns, and capes supplied to dress up and be photographed in. Tie helium balloons to the back of some chairs to create height and drama.’
