Ariel Sparkle Classic Kids Mermaid Costume

We have to start with a “Princess Ariel” mermaid costume, don’t we?  Disney’s The Little Mermaid, very loosely based on Hans Christian Andersen’s story of the same name (see Wikipedia article here for a good summary), made the idea of mermaids exciting and popular with little girls. The beautiful red-headed mermaid who dreams of love with human Prince Eric is a very popular princess for dress up.

This gown by Disguise is rated an average 4.4 / 5 stars by 80 reviewers.

Customers are thrilled with the quality of this gown,  and their daughters are too! A few notes I gleaned from the reviews: Buy a size up for easier walking, the color is a more vibrant green than that seen on the image (more like Ariel’s color), and if the top is slightly “itchy”, have her wear a tank top underneath.




ReliBeauty Girls Sequins Little Mermaid Costume

ReliBeauty is becoming known for their great quality dress up clothes – the reviews on their gowns and costumes are really, really good! This mermaid gown with “scale-like” sequins another very well liked dress up choice – you can count on getting more than just one night of play time out of it!

What I like about this costume is that it’s suitable for a CHILD. It’s not “too old” or “mature” for a young girl, but still has that distinct mermaid look on both top and bottom. It’s comfortable, designed with kids in mind who like to actually MOVE in it, and very pretty! (And so is the matching headband that comes with it!)

This girls mermaid costume is rated an average 4.5 / 5 stars by over 215 reviewers.




JiaDuo Kids Girls’ Princess Mermaid Dress Party Costume

Note: This costume seems to run rather long – even the manufacturer says so. If you have a taller child, it might be exactly the one you need! Check out some of the reviewers pics of the real thing by clicking through to Amazon below – it’s so, so cute!

The deep blue/purple color is seriously gorgeous, isn’t it? I wouldn’t mind wearing this one myself! 🙂  Reviews on it are very good! Check them out by clicking through below!

Little Girls Princess Dress Up Mermaid Costume

Here is a gown for those of you who don’t want to risk your little girl tripping in a tight mermaid style costume. It’s a gown that is styled to look like a beautiful mermaid with the purple “fins” and the blue skirt that flows like water.

This is a stunning princess dresses for little girls with real “garment” material (not cheap Halloween costume stuff) and it has very high reviews. You won’t be sorry with this one! It’ll get lots of play time if your daughter is into dress up!

This one is a bit different – it actually IS a mermaid tail. And it’s good in water! It’s the perfect mermaid costume for photo shoots or dress up play IN THE BATHTUB or shallow pool. Tons of fun!

This mermaid tail is made of sparkly spandex-type material, is available in several colors and shimmers much like a “real mermaid’s tail” would! You can get it in sizes 2T-14!

This girls mermaid costume is rated an average 4.0 / 5 stars by 60 reviewers.

    Hi Marlaine,
    My daughter loves dressing up. She loves mermaids especially. I think she will love the mermaid costume with the tail. Then she will probably love them all. It’s great there is a good variety to choose from with so many colours available.

    Thank you
