Mermaid Tails for Kids- Buyers Guide
There are hundreds, if not thousands, of mermaid tails available out there, from the cheap cloth costume mermaid tails to the professional swimmer’s gear. With all these options, choosing the right mermaid tale for your children can be daunting.
To help you make your decision, here are the most important things you need to consider when buying a mermaid tail for kids:
What’s included?
Most brands offer both individual fins and full sets in varying price ranges and quality, so one of the first things you need to ask yourself is what exactly you need. Do you just need a tail, or would you prefer a full getup including a monofin?
The advantage of getting a complete swimming set is that you’re sure that everything matches perfectly, so your kid can look pretty and put together, and you can take the perfect pictures. Then again, you can always partner up any tail with a plain or muted color swimsuit, and it will look just as nice.
An individual mermaid tail is definitely cheaper than a set, and if you have a huge budget to spare, you can spend it on getting the best quality. While it’s easy to find an affordable set, you’re almost always sure to get a better quality mermaid tail for the same price.
How much are mermaid tails?
Speaking of the price range, mermaid tail costs can vary greatly, depending on many factors such as fabric and quality, warranty, manufacturer, popularity, demand, inclusions, and so on. We’ve found tails and complete sets for as low as $40.
The more expensive fins range from $50 to a little less than $100. Anything higher than that is either luxury brands or professional-grade swimwear for mermaid performers. These are almost always premium quality and offer warranty or free product replacement.
While getting the best quality tail seems ideal, it can definitely be pricey. You also need to consider whether it’s worth shelling out that much money. For one thing, little kids will quickly outgrow their tails, unlike teens which can grow into adult mermaid tails that they can wear for years to come.
Is it swimmable?
One important factor that affects the price of a mermaid tail, and whether it’s what you’re looking for, is whether it’s made for swimming, or just for general costume purposes.
Most fins are made with swim fabrics such as silicone or spandex, meaning, it’s light, stretchable, fits snugly, dries easily, and enables the wearer to move around in the water with ease.
You’ll also find cheap tails that are essentially just cloth printed with scale patterns. These are good options for photoshoots and costume parties that don’t involve the wearer getting wet or taking a dip in the pool or ocean.
The right material
When it comes to what the tail is made of, there is no single right material for everyone. This, again, depends on what you want to use the mermaid tail for. Is it just decorative, or do you want the wearer to be able to swim in it?
It needs to be fabric kids can swim with, like silicone, if you’ll use the mermaid tail for swimming, and just about any fabric for all other purposes. Of course, the quality of different swim fabrics also differs, so be sure to check the specifications, such as material thickness, weight, stretchability, and so on.
Moreover, check the tail tip’s quality. This is what gets stretched when the mermaid tail is fitted with a monofin, and what gets dragged around when the wearer is walking around with the tail on. Wear-resistant tail tips are more expensive, but they are worth it in the long run.
Mermaid tails for different ages
As you have seen throughout this list, mermaid tails are available in various sizes to accommodate all ages, from toddlers to grown adults. That said, if you plan on letting your kid swim using the tail, it’s best to wait until they know how to swim on their own first, just to be safe.
There are also different designs and styles of mermaid tails for 7 or 8-year-olds, as compared to, say, 3-year-olds, and teens. Tails for younger children are typically ankle-length, open-bottomed fins, while those for older kids can be fitted with a monofin for better swimming ability.
What’s important here is to check the manufacturer’s size chart so that you can be guided accordingly in choosing the right size for your kid. Don’t just base on the recommended age- check the measurements to see if the mermaid tail will fit.
Durability
Now, how you define “in the long run” depends entirely on you, but what’s important is that the tail at least lasts your kid an entire summer, even if he or she decides to wear it every single weekend.
What you want here is a tail material that does not wear and tear easily. For one thing, the tail should return to its original shape after it’s stretched, and it shouldn’t look like it’s one pull away from ripping apart, especially if you plan on using the washing machine to wash the mermaid tail regularly.
It should also be fade-resistant, especially since the mermaid tail will be submerged in chlorinated or salty water for long periods of time, then laundry detergent afterward. You want a mermaid tail that looks good as new even after several wears and washes.
The right color
Finally, once you’ve settled on the right mermaid tail for your kids, you need to decide on the color and design that will perfectly suit your children’s tastes and preferences. Would they want something classy and elegant, like a true under-the-sea princess, or something fun and quirky they’d want to splash around in all day?
Any option on the side of blue is a sure, no-fail option for a mermaid tail, or you can get one in your child’s favorite color. Better yet, show your kid the options and let them take their pick!
To summarize
Mermaid tails are the perfect getup for your kids’ ultimate under the sea experience, whether it’s for a simple photoshoot, a Halloween costume party, a summer pool party, or to add fun and excitement to a typical dip in the pool.
As you’ve read this guide, you’ll come to find that there are many different kinds of mermaid tails for various occasions, uses, and budget ranges. In order to pick the right one for you and your kid, you need to go beyond the price range, but also take into account things like the tail’s purpose, material, quality and durability, suitable age, and color.
