Mermaid Tail Photos and Models


If the idea is to choose a mermaid tail model that looks as close as possible to fish scales, surely the silicone versions are the best option.

The advantage of this type of tail is that it wears well, is comfortable to wear and still looks very similar to the models used in movies, cartoons and even soap operas (who was never drooling over the Ritinha character dressed as a mermaid in the soap opera β€œA ForΓ§a do Querer” ?).

However, all these advantages come with downsides as well, and one of them is that the silicone mermaid tail is usually the most expensive version of the models and can still be quite heavy to swim with. So, it takes training!

For those who love the idea of ​​doing crafts and DIY (Do It Yourself – Do It Yourself), it’s worth getting inspired by the crochet mermaid tail models.

This type of tail is ideal to stir the imagination and be part of a costume, turn into a blanket or even a look for photos, but it is not the best version for those who want to use a mermaid tail to swim.

As the model is made from string, which is a cotton base, when wet the tail absorbs water, making movement difficult. Another downside of swimming with the crochet tail is that it is not structured, which doesn’t help much in the movements of the mermaid swim.

The use of the accessory can be for different times, and one of the possibilities is to use the piece in a blanket style.

Instead of using traditional blankets, this type of blanket has a tail shape and is perfect to cover your legs on the sofa and still make your rest time more charming.

This type of garment can be made of knitting (wool), microfiber or even a cotton fabric, as if it were a comforter.

For sure this is a type of piece that will be successful with children and adults, after all it is an amazing cover!

To transform into a mermaid, there is no lack of tail model options, and the variety of fabrics allows you to create a wide range of models of the accessory.

Among the ideas, it is worth using felt to make a simple and cheap tail; fabrics with sequins, which makes the tail shiny and beautiful; cotton fabric and even glossy versions that resemble fish scales.

The choice of fabric influences the purpose of the tail, as some versions can even be used for swimming, while thinner models, such as versions with sequins, are better for creating mermaid looks and costumes.

To Swim / With Monofin

For those who want to further incorporate the mermaid reality and go beyond a simple fantasy, you can take advantage of the mermaid tail to swim.

To fall into the water with a tail, the model must be adapted for this type of task, and in this case the tail must be made of material that does not become heavy with water absorption and have a structure that facilitates movement when swimming – like the monofin.

The monofin is an accessory that gives the final structure to the tail, and allows you to make movements in the water.

Oh, and it’s a warning for those who think it’s just falling into the water with your tail and turning into a mermaid. The accessory can get heavy and as the legs are more restricted in movement, it can be difficult to swim. So, before finding yourself a mermaid, it’s good to train and even take a course with mermaid tail swimming techniques.
