Best Nautical Themed Cosplay Ideas

1. Captain Jack Sparrow Cosplay

Captain Jack Sparrow is an essential part of any ocean-themed costume collection. Johnny Depp's portrayal of the legendary pirate has become instantly recognizable because to the actor's impeccable taste and obvious passion for all things maritime seen in the Pirates of the Caribbean film series.

To achieve this look, you will need a long, curly wig (brown is preferred), thick eyeliner, and a striped shirt. You can get these things at any Halloween store or on the internet.

Pants should be a dark, flowing fabric, and black is a safe bet. In addition, don't forget the extras! The only things more important than a pirate captain's helmet and sword are his compass and his map.

You are now equipped to set out on your own journey; just remember to avoid Davy Jones' locker.



2. Luca Paguro Cosplay

The titular character from Pixar's smash blockbuster "Luca" is one of the most recent additions to ocean-themed outfits. When Luca, a young marine creature, arrives to land, he assumes a human form. Another aquatic creature, this one passing as a person in an Italian coastal villa, becomes his companion.

Cosplayers' costume makeup talents are put to the test when attempting to emulate the look of a half-human, half-sea creature.

If you want to emulate Luca's ocean-inspired style, you'll need a blue or green wig, some colored contact lenses, and a whole lot of highlighters. Traditional Italian attire consists of a white shirt and red pants or a dress.

3. Nico Robin Cosplay (One Piece)

Nico Robin is a major player in the One Piece anime and manga. She is an archaeologist who decides to tag along with the Straw Hat Pirates as they search for the mythical One Piece treasure.

Robin typically wears a plain black dress with puffy sleeves, and her long, wavy hair is pulled up into a chic updo. Even though Robin's attire looks simple at first glance, there are a few critical elements that can make or fail a Nico Robin cosplay.

An appropriate fabric must be selected for the outfit first. Make sure the dress fits nicely, and use a lightweight black fabric to mimic the drape of Robin's gown. Getting a well-fitted or tailored dress is preferable because of the hassle of trying to style a loose one.

Finally, don't forget the finishing touches! Make sure your Robin cosplay features the iconic swallowtail brooch. If you follow these guidelines, your Nico Robin cosplay is guaranteed to shock even the most devoted One Piece fans.



4. Monkey D. Luffy Cosplay (One Piece)

Among anime and manga fans, one of the most well-known nautically-themed cosplays comes from the series One Piece. The protagonist of the show, Monkey D. Luffy, wants nothing more than to rule the high seas as Pirate King. In order to obtain the legendary treasure known as One Piece, he embarks on a trip with his motley crew, the Straw Hat Pirates.

To get the Monkey D. Luffy cosplay look, you'll need a red or orange shirt and shorts and a yellow straw hat. You can easily find these items online or at your local costume shop.



5. Cast Away Cosplay

The plot of Cast Away revolves around a man who survives a plane disaster only to find himself on an isolated island. He is stranded on an island with only his trusty Wilson volleyball for company.

Among our picks, this is one of the most imaginative ocean-themed cosplays. In order to pull off the outfit, you'll need a volleyball and a white shirt or pants. A Wilson volleyball can be found at any sports goods store or ordered online.

6. Jack and Rose Cosplay (Titanic)

One of the most famous movies ever made on a couple's love story is Titanic. In this tragic love story, the protagonists, Jack and Rose, are two lovers whose paths were destined to intersect on the doomed journey of the Titanic.

You'll need to track down a long, formal dress for Rose and a suit for Jack if you want to construct a cosplay of Rose and Jack. Make careful to give the impression that they have been through a rough journey at sea by giving them a torn appearance.

Be careful to reenact some of the film Titanic's most memorable moments if you want to portray the film's enchantment accurately. The initial encounter between Jack and Rose, their dance in the ballroom, and the iconic scene in which Jack sketches a portrait of Rose are all wonderful moments that can be re-created.



7. Ariel Cosplay (The Little Mermaid)

The Little Mermaid is an instantly recognizable character to dress up as for any ocean-themed party or event. There is no better way to go "Under the Sea" than the iconic mermaid who stands out with her radiant red hair and sea shell bra.

There are a few things that make a Little Mermaid costume stand out. First, of course, is the incredibly detailed mermaid tail. Many cosplayers opt for a tail skin, which gives the illusion of a natural fishtail. But the genuinely dedicated go the extra mile and create a custom-made tail they can swim in.

The second is the intricate wig. Most Ariels choose to style their hair in long, flowing waves. To get that iconic long, you will likely need to get a red wig in Ariel's style, or dye your hair bright red.

And last but not least is the makeup. Many cosplayers use special effects contacts to get that perfect Mermaid look. With all of these elements put together, it's no wonder Ariel is one of the most popular characters to cosplay!

8. Ursula Cosplay

Looking for a nasty sea witch to cosplay as? Ursula from The Little Mermaid is a great option! Ursula, the sea witch, steals Ariel's voice and gives her legs in exchange. Her large purple frame, tentacles, and sinister laugh have made her notorious.

To appear like Ursula, you'll need a purple body suit and some artificial tentacles. This sort of thing is available at any costume store or on the internet. Ursula's look would be incomplete without the wig, too. You should either buy a long, black wig in her style or try to achieve the same look by styling your own hair.

Makeup should include a strong smokey eye and purple accents. Remember the false eyelashes! Ursula's style would be lacking without her thick, lengthy eyelashes.



9. King Triton Cosplay

Ariel's dad, King Triton, is the ocean's monarch and the one who raised the young mermaid. The trident he carries, the ocean robes he wears, and his regal bearing have all made him famous.

A trident, some sea garb, and a crown are all you need to channel King Triton. You can get these things at any Halloween store or on the internet. Makeup should include a dramatic smokey eye and highlights that recall the sea.

Don't forget the beard, either. Fake facial hair, in the form of a beard or mustache, should be included in your costume as King Triton is famous for his magnificent facial hair.



10. Namor Cosplay

Namor, the Sub-Mariner, is the ideal costume choice for anyone seeking for an exciting aquatic outfit. Because he's a mutant, he can breathe underwater and has tremendous strength. This man has a well-deserved reputation for both his rage and his rash actions.

Wearing a green body suit and accessorizing with yellow will give you the Namor look. You may find accessories like this at any Halloween shop or online. Get a short black wig or do your own hair in the waves he's known for to pull off the look.


11. Aquaman Cosplay

The popularity of DC Comics' Aquaman has skyrocketed in recent years, making him one of the franchise's most recognizable heroes. Aquaman's breakout performance in Justice League propelled him to superstardom. This has led to an uptick in demand for Aquaman costumes and cosplay.

There are several possibilities if you want to be Aquaman for Halloween or a comic convention. Costumes of Aquaman typically have his trademark orange top and green bottoms, but you can also go shirtless for a more modern look. Other costumes feature Aquaman's armor for a more genuine feel.



12. Mera Cosplay

If you are looking for a sexy marine-themed costume, or perhaps want to pair up with Aquaman for a splashy couples costume, Mera's sleek costume is a must-have. She has the superpower of regulating the flow of water and is thus a superheroine. She has a reputation for being quite feisty and witty.

To imitate Mera's attire, don a green bodysuit and accessorize with yellow. This sort of thing is available at any costume store or on the internet. Get a short, red wig in her style, or make your own hair into the waves she is known for.

Makeup calls for a smokey green eye with some yellow highlights. Remember the false eyelashes! Mera's appearance isn't finished unless she has her signature long, thick lashes.


13. Black Manta Cosplay

Black Manta is the iconic supervillain who battles Aquaman under the sea. His signature look is a black and red suit with a red mask and a red helmet that completely encloses his head. Black Manta has appeared in several comic books, cartoons, and movies (both animated and live-action) over the years, but his history is shrouded in mystery.

Many DC Comics fans express their fandom and enthusiasm by dressing as Black Manta for cosplay conventions. If you put on the correct outfit and makeup, you can pretend to be Black Manta for the day.


14. Mermaid Man and Barnacle Boy Cosplay

15. Steve Zissou Cosplay (Life Aquatic)

If you're a fan of the Wes Anderson film The Life Aquatic with Steve Zissou, then you know that the character's style is as iconic as the film itself. And what better way to channel your inner Steve Zissou than by donning a costume inspired by the aquatic adventurer?

There are a few critical elements to a good Steve Zissou cosplay. First, you'll need a red beanie - an essential part of any self-respecting Zissou outfit. You'll also need a blue sweatsuit (preferably with some nautical stripes) and brown Timberland-style boots.

Many cosplayers carry a toy gun or other prop to complete the look. While there are many ways to interpret the character, the most important thing is to have fun and enjoy yourself.

With these key items in place, you'll be ready to tackle any adventure - real or imagined - just like Steve Zissou himself. So go forth and explore, and don't forget to take plenty of pictures along the way!

16. Davy Jones Cosplay (Pirates of the Caribbean)

Davy Jones is the iconic villain of the Pirates of the Caribbean franchise and a challenging cosplay option that will make partygoers quake in their skivvies. Davy Jones cosplay requires exceptional costume makeup to make it work to recreate the monstrous look of the iconic character.

You will also need a claw and peg leg prop to pull off. But it's worth the effort! You will be the scourge of the sea!

17. Moana Cosplay

In the 2016 Disney animated feature film of the same name, Moana plays the lead role. Moana is an adventurous teenager on a mission to save her island and discover who she really is. She runs across the demigod Maui and they set out together to traverse the ocean and put a stop to the villain Te K.

You'll need a brown wig (or brown hair colour) a red Polynesian outfit, and a flower crown to cosplay as Moana. You can get these things at any Halloween store or on the internet.

Keep the makeup minimal as you want to replicate her fresh and simple ocean-inspired look. A blue eyeshadow, coral lip color, and a generous application of highlighter will do.

As with Moana herself, you will feel prepared to take on the world once you have these things in place.


18. Maui Cosplay

In Disney's 2016 animated film Moana, Maui plays the role of the demigod sidekick to the titular character. Maui, a shapeshifting trickster, assists Moana in her oceanic quest to defeat Te K.

You need Maui's long, flowing hair and his buff physique if you want to cosplay as him.

It's also recommended that you design tattoos in the style of Maui. Temporary tattoos can be created with tattoo transfers or, if you're feeling particularly daring, you can draw your own designs. Make sure to use liberal amounts of black eyeliner to achieve that striking, tattooed appearance.


19. Water World Cosplay

waterworld cosplay

The events of Water World take place in the future, after the polar ice caps have melted and the earth is completely submerged in water. People in this post-apocalyptic society will have to adapt to life on water, with floating towns and an economy based on marine resources, which makes for a very grungy and disheveled appearance for most Water Worlders.

There's a lot of room for innovation with this costume as there is no single character that really stands out. Get some dirty old used clothes, shred them up and soak them in dirty to capture that well-worn post-apocalyptic appearance that will amaze fellow cosplayers and party goers.


20. Captain Quint Cosplay (Jaws)

The 1975 horror classic Jaws is universally recognized as one of the first blockbusters in film history. In this movie, a great white shark causes havoc in a little Massachusetts hamlet.

The film's protagonist, Captain Quint, is a professional fisherman who is tasked with killing the shark. Finding a yellow raincoat and pants to go with it can help you complete your Captain Quint cosplay. A crimson scarf will give a splash of color to the ensemble.

Get Captain Quint's signature hairstyle to complete your transformation. To imitate the style, put your hair in a middle part and slick it back.



21. Baby Shark Cosplay

There's no denying that the infectious tune of "Baby Shark" has just swept the globe, as any recent parent can attest. This is a great costume to wear for young parents and families with young children. Dress up together as Baby Shark, Daddy Shark, Mommy Shark and more for a ton of fun. Be sure to sing the song as you trick-or-treat around the neighborhood to really set it off right.
