Mermaids have drifted through mythology, folklore, film, and fantasy for centuries, always hovering between danger and desire, mystery, and allure. While you might immediately think of Disney’s The Little Mermaid – either the 1989 animated film or the 2023 live-action remake – that particular story is based on Danish author Hans Christian Andersen’s 1837 fairy tale.
But the concept of the mermaid itself predates modern pop culture by thousands of years, appearing in Greek mythology and later in European folklore – in fact, the first use of the word “mermaid” is in Geoffrey Chaucer’s The Canterbury Tales back in 1390. Go even further back to the 3rd century BC and you’ll find sirens, whose songs were so alluring that seafarers sailed their ships straight into rocks in order to get closer – ultimately wrecking and drowning. Talk about powerful women!
Today, the mermaid is one of the most recognisable symbols of fantasy and seduction. But how have mermaids moved from fairytale to fetish?
Modern interpretations have reshaped how we see mermaids. The Disney version turned her into a romantic heroine navigating desire and identity, while more adult retellings have leaned into darker, more intimate interpretations. Even films like Splash, the 1984 romantic comedy starring Tom Hanks and Daryl Hannah, played with the tension between fantasy and real-world intimacy in a way that made the mermaid figure feel both magical and sensual.
More recently, mermaids have reappeared across fantasy television, cosplay communities, ASMR on TikTok, and online subcultures, often blending sensuality with myth. The imagery is striking, but the appeal is rarely just visual.
A mermaid fetish often centres on transformation and otherworldliness. The idea of being part human and part sea creature taps into themes of fluid identity, surrender, and freedom from ordinary constraints. Water has long symbolised emotion, depth, and the unconscious. A mermaid, existing between land and sea, embodies duality. She belongs everywhere and nowhere – between worlds and yet inhabiting both.
For some, the appeal lies in the visual aesthetic: Shimmering tails, flowing hair, bodies gliding through water with effortless grace. For others, the draw is more psychological. Mermaids are powerful yet elusive. They can lure, captivate, and disappear beneath the surface. That dynamic of control and mystery can feel intoxicating.
Mermaid fetishism can also intersect with themes of dominance and vulnerability. A creature of the sea holds power in her own environment, yet becomes vulnerable when removed from it. That shifting balance can be part of the erotic charge. The water itself introduces elements of restriction, weightlessness, and altered movement, which can heighten sensory awareness.
For others, the fantasy is less about power and more about escape. The ocean represents distance from social rules, expectations, and judgment. Imagining intimacy beneath the surface, suspended in water, suggests privacy and detachment from the ordinary world. It becomes a space where different rules apply.
Transformation is one of the most common threads in fantasy-driven fetishes. Becoming something else, even temporarily, allows people to explore aspects of themselves that feel inaccessible in daily life.
If you're keen, cosplay is a great place to start. Adult-sized mermaid costumes and even mermaid-tail-shaped flippers are all available, particularly online. Just check the materials are water-safe if you plan to go to the beach or swimming pool, and be sure that you are able to move safely in your costume - narrow mermaid tails may look amazing draped over a picturesque rock, but can you walk back to the car in it? Or can you swim safely in it if you're going to actually be in the water? Remember, safety comes first, and this is one of those rare fetishes where water safety is an important aspect!
If going full-fins is too far, mermaid-themed makeup might be a look you could try, with shimmery eyeshadow, stick-on pearls, and even a long wig adorned with seashells and starfish beads. The colour palette itself - liquid lavender, seafoam green, ocean blue, with sparkles and hints of mother-of-pearl - is soothing and tranquil, and gives your skin an otherworldly glow that lends itself well to fantasy play.
Above all, the mermaid embodies transformation without losing sensuality. She is not hiding her body – she is amplifying it, reframing it, mythologising it. In that sense, the fetish is less about fins and scales and more about fluidity (literally as well as intimately).
