Whether they want to shimmer like a fairy-tale princess, rule the sea like an underwater queen, or add a spooky siren twist to their look, we've got the perfect outfit for every little ocean dreamer. These girls' mermaid outfits are perfect for Halloween, dress-up play, themed parties, or even just a little everyday under-the-sea fun—because let's be honest, being a mermaid is a full-time job.
From a classic Ariel mermaid costume to unique and spooky mermaid outfits, these costumes are dripping in mermaid magic. Sparkling tails, seashell tops, and ocean-hued fabrics make every little mermaid feel like they just swam in from a magical kingdom. If they love the Little Mermaid, they can channel their favorite red-haired princess, or if they want to create their own underwater character, there are plenty of colorful, stylish options to choose from.
For those who prefer a little edge with their mermaid look, a girl's skeleton mermaid costume or a siren mermaid costume brings an eerie twist to the classic sea queen aesthetic. These costumes are perfect for girls who love a bit of spooky mystery while still keeping that enchanting mermaid vibe. Add some shimmering face paint and a dramatic wig for a look that's equal parts haunting and mesmerizing!
