Mermaid tails for adults – Buyers Guide

woman with mermaid fin in pool

Picking out a mermaid tail is no easy task- trust us, we’ve been there. There are hundreds, if not thousands, of mermaid tails available online, from the simple and elegant to the unique and bizarre. And, the price range is steep, too!

So, how do you pick the right tail for you? Read this guide and you’ll find out! We’ll help you understand the basics of swimming with a mermaid tail, the different factors you need to take into account when buying a mermaid tail, and other tips and tricks for the best mermaiding experience.

What’s a monofin, and do I need one?

A monofin is the thick, flipper-like insert that fits in a mermaid tail so you can swim safely. It’s typically made of plastic, fiberglass, or carbon fiber snugly fits in the fluke part of the tail and may be securely attached to your feet through straps or stretchable holes.

Much like flippers, monofins are designed to help propel you underwater, which is really important since your feet are joined together, making it harder to move around in and out of the water.

Essentially, it’s what makes your mermaid tail swimmable. Most mermaid tails automatically come with a monofin upon purchase, although you can also buy one separately.

What is the right material?

Mermaid tails can be made from different materials, some of which are suitable for swimming, and some are purely for costume purposes. The most popular mermaid tail materials are polyester, nylon, and spandex, or a combination of these.

They’re pretty much like most swimsuits, so they are lightweight, stretchable, comfortable to wear, and swim around in, easy to take off, and dries easily. So, you’re getting a high quality, machine washable mermaid tail that is pretty and affordable.

You’ll also find some latex and rubber mermaid tails, although these are less common and are not as great for swimming. Of course, if you just want a tail for a themed photoshoot or a costume party, you can settle for a tail made of cloth fabric.

The best material, however, is silicone, since it’s the most realistic looking and most durable. A silicone mermaid tail is a high-quality custom-fitted tail that’s a little heavier than others and needs a bit of practice to swim in.

Other mermaid tail materials include waterproof plastic and neoprene, which are mostly used on the tail’s monofins.

How much is a fin?

As we’ve mentioned earlier, mermaid tails and monofins often come as a set. There are many cheap tails and tail + fin sets that are under $50, and some of these are realistic mermaid tails too, like a few included in our list.

You’ll also find more expensive mermaid tails that cost upwards of $100 or $200. These are usually professional mermaid tails, many of which are custom made by special tail makers, such as silicone mermaid tails.

When it comes to individual monofins, these can cost anywhere from $20 to $100+. These prices depend on the brand, material, and quality of the product. Here’s a tip: if you’re a little tight on the budget, you can start by making your own fin for free!

What is the right size?

Just like anything you wear, mermaid tails come in a variety of sizes, from child sizes to adult sizes, including plus size mermaid tails. When it comes to choosing the right fit for you, you need to measure out the length and width of your legs and feet, as well as your waist and hips.

Getting the right fit and size is important, especially if you don’t want to end up with a tail that is way too small it won’t even ride past your knees, or a tail too big that it slips off while you’re swimming.

What you want here is a tail that feels sleek, snug, and comfortable, so it looks realistic on you, and you can move around well in the water.

What color to choose?

Picking out the tail color is most likely what you have been looking forward to all along, and it may also be the most difficult decision you’ll have to make, especially since everything looks pretty and dazzling.

The most common mermaid tail colors are blue, green, purple, yellow, and orange, since these resemble the colors of most sea creatures. We suggest picking a color that works well with most of your swimsuits, so you can always look put together and more mermaid-like.

More than color schemes, it’s also a must to pick a good design, print, or pattern. Some tails feature plain and simple tails that look realistic and timeless, while some others have trendier and more out-of-this-world designs. Pick one that fits your personality, and you’ll still like a couple of years down the road.

What is mermaiding?

To put it simply, mermaiding is pretending to be a mermaid by wearing a mermaid tail and matching accessories, whether for mermaid swimming or simply as a costume for a fun fantasy-filled day ahead. With the right mermaid tail, you can live out your childhood fantasy of being an under-the-sea princess.

If you really want the full mermaiding experience, find a mermaid tail that you can swim in, a good quality monofin to match, and the best accessories to complete your look!

Can anyone swim with a mermaid tail?

Yes! Anyone, young or old, can swim in a mermaid tail, as long as they know how to swim, their mermaid tail has a monofin to propel them in the water, and they do a bit of practice swim wearing the tail to find the right kick and motion.

In fact, even tiny kids can swim like a mermaid! There are plenty of wonderful mermaid tails for kids out there, so you and your little ones can have as much fun as possible. Just pick out a swimmable mermaid tail, make sure it comes with a monofin, and don’t leave your child unattended while in the water.

Where can I swim with my mermaid tail?

In theory, you can swim with a mermaid tail anywhere, including the ocean. But, you should only do so if you are an expert swimmer, you are 100% familiar with the area, and you have plenty of company to watch over you.

This is because swimming with a mermaid tail is difficult, and can even be dangerous, since how you swim significantly differs from swimming with two feet. So, it’s advisable to only use your mermaid tail for the pool, where you’ll still have a lot of fun while being safe and sound.

What are the different types of mermaid tails?

There really is no one way to classify mermaid tails according to type, except for swimmable, non-swimmable, and walkable, all of which are largely determined by the type of fabric the tail is made of, whether it has or can fit a monofin, and whether it has open bottoms.

That said, mermaid tails can be made out of various materials such as fabrics and silicone, feature different designs from simple to quirky, and have different textures, such as matte, silky, or covered in glitter.

How can I look like a mermaid?

Down to the *most important* question of all, how can you look like a mermaid? Well, we’ve got both good news and bad news for you. The bad news is, a mermaid tail, no matter how realistic and form-fitting, just won’t cut it. But, the good news is, with the right accessories, it’s easy to pull off a true-blooded mermaid look!

An easy way is to go for a full-on mermaid suit, but if you want something more realistic, and you’re willing to exert a bit of extra effort, a mermaid tail and matching swimsuits are your best bet. You can find plenty of mermaid tails that come with tops and (even bottoms) to complete your look.

The next step is to glam it up with the right accessories, such as sea-inspired bracelets and necklaces. Of course, don’t forget the hairpiece, whether it’s a tiara, a flower crown, or a headwrap.

Finally, if you want to go all the way, you can experiment with temporary hair colors so you can have a mermaid colored dyed hair. If you do this, try to find waterproof options, and always make sure to do a test first to prevent any allergic reactions.

Overview

Choosing a mermaid tail is both an exciting and daunting task, but with the right knowledge, a keen eye, and attention to detail, you can easily find the right mermaid tail that fits your frame, your needs, and your budget.
