Mermaid cosplay ideas
As part of your transformation into a mermaid, consider trying out your new look with a mermaid costume. Having a tail instead of legs would be a big chance for anyone who succeeds in becoming a mermaid. As a bonus, you have a great mermaid costume for a Halloween or masquerade party. Such an enchanting costume would be quite the attention-grabber at any event you might be attending.

A mermaid costume can be put together quite easily. It’s entirely up to you as to whether you choose to buy one, have one made to your specifications, or even sew a mermaid costume yourself! Everything can be chosen to suit your preferences, from tail colours, fabric and wig styles right down to finding the perfect accessories for your mermaid costume.

Make a mermaid costume

For those skilled at sewing, there are several commercial mermaid tail patterns available. This makes it easy to sew your own mermaid costume in the exact colours and fabrics you choose.

First, decide if you plan to swim in your mermaid tail or if this is a traditional costume. This will dictate the type of pattern you need and the best fabrics to make your mermaid costume. Then you should select a colour scheme for your costume. Blues and greens may be traditional mermaid colours, but if pink and orange are your favourite colours, it’s easy to find the perfect mermaid costume fabric to suit your preferences.

Sketch out a rough design of your costume — fin placement and shape, top (or not), any accessories you might like. This will aid you in making the perfect unique mermaid costume.

Mermaid costume patterns

Some of the traditional mermaid costume patterns currently available:

Most of these patterns are for “walking tails”, which are perfect for mermaid parade attendees who intend to walk in the parade. The baby mermaid crochet pattern is perfect for baby photoshoots!

Mermaid tail fabrics

Once your costume design has been selected, choose a suitable fabric to make your mermaid costume. Some excellent choices would be anything with a fish-scale print fabric (of course), but also vinyl, spandex, or pvc fabrics. If you plan to make a “walking mermaid tail”, you might try foil sequin fabric as well.

Swimmable tails

If your desire is to swim in a mermaid tail, use a swimming monofin to emulate the experience of having a tail. When making a custom mermaid tail, design the tail fin area to accommodate your monofin. This is easier to do with a sewn mermaid tail than a molded latex or silicone tail which cannot be altered after the mold is cast.

It is also highly recommended to have a swimming tail professionally made if you plan to swim in it. Swimming tails are usually made of latex or silicone, which takes some time and skill to work with. You do not want to handle such toxic chemicals in your home without a lot of safety precautions. A professional tail maker will not only be best equipped to achieve the correct fit of your tail for safe swimming, but will also be prepared to deal with the chemicals in a safe manner.

Swimming tail safety

When you are ready to swim in your tail, be certain to have at least one other person with you. Never swim alone in a mermaid tail. Accidents happen quickly; always have a handler with you who is ready to assist you with any difficulties.

Swimming in tail is a basic dolphin kick (knees together, move lower legs as one unit). This will take some practice. Please try it without the tail first (monofin only, if you are using one) until you have the hang of it. For additional help in swimming, try a pair of webbed swim gloves in increase your speed and mobility. You can even find swim gloves in colors that will match your mermaid tail!

Buy a mermaid costume

If you can’t sew a seam for anything or simply don’t feel creative when it comes to designing your own costume, choose from the many commercial pre-made mermaid costumes. While these are far more limited in sizes and colour choices, an off the rack mermaid costume is perfect for costume parties, Halloween, and Mardi Gras.

You can easily customize your mermaid costume with accessories and props to make even the most common commercially made costume uniquely yours.

Mermaid fashion accessories

Once you have a basic mermaid costume assembled, it’s time to choose just the right accessories to complete the look! Think about sea shells, freshwater pearls, even long strings of water-like crystals when selecting accessories for your mermaid costume. These little touches can make the difference between wearing a standard stock mermaid costume to an event and having an eye-catching unique mermaid costume.

Mermaid wigs

Those would-be mermaids with short hair would benefit from a long-haired wig, perhaps in a fantasy colour.

Mermaid tops

If your costume is just the tail, you’ll need a top to go with it. Either wear a bikini or tank top, or the more daring might choose a sea shell bikini top to appear more authentic.
A simple bikini with your tail will allow for quick removal of tail in the event of an accident. Don’t restrict yourself to a bikini top with your mermaid tail, though. If you’re staying on dry land, a corset or halter top can make a perfect tail accessory.

Mermaid jewelry

You can add shell leis for necklaces and bracelets, or some inexpensive freshwater pearls or crystal jewelry would work just as well.

Mermaid purses

You will need someplace to stash your wallet and keys while attending a mermaid event. Why not carry a handbag or purse that any mermaid would love?

Other mermaid accessories

Sometimes it’s the small things that can complete a costume. A seaweed boa to wear, a shell compact for your mirror, perhaps a few loose shells or a large starfish to carry?

Mermaid makeup tips

The look of your perfect mermaid costume can be best completed with skillfully applied mermaid makeup. It is important to choose makeup colours that compliment your costume. Traditional mermaid colours are greens and blues, but if you have chosen a mermaid costume in shocking pink or gold, select cosmetics that match. Enhance your makeup with stick-on crystals and jewels.

Those going for a less-human mermaid appearance will want to paint on scales and include latex prosthetics such as webbing for ears and fingers. You are limited only by your creativity!

Mermaid costume props

If you feel your mermaid costume needs something more, you can also carry props while wearing it. A mermaid might be guarding an undersea treasure chest full of jewels. She might also be caught up in a fishing net with seashells and little plush fish friends. Of course, there is always the traditional mermaid image of her carrying a comb and mirror.

As always, choose the best props to suit your particular mermaid character.
