Lisa's Dark Siren Halloween Look Puts Thai Designer UNKUNIYA in the Spotlight

A Thai designer behind the shimmering scales

Lisa's Halloween transformation on October 31, 2026, put a Thai fashion label at the center of an elaborate aquatic fantasy. The BLACKPINK singer appeared as a Dark Siren, wearing a sculpted mermaid tail created by Wutthichai Kaewla of UNKUNIYA in collaboration with Nanist, the stylist leading the costume team.

The photographs attracted more than 2.1 million Instagram likes within six hours. Beneath that attention was a costume built around specific details: embroidered scales reflecting the light, flowing fins, and orange and copper shades tucked beneath a dark outer layer. A black crystal crown, bright blue contact lenses and pointed fangs completed the transformation.

Lisa, whose full name is Lalisa Manobal, made the tail the defining feature of the character. Its large silhouette extended the transformation beyond her face and clothing, while makeup carried the aquatic textures across her arms and hands. The result connected the garment, accessories and body painting into a single creature.

The photographs also brought the people behind the costume into view. For UNKUNIYA and Nanist, the attention attached recognizable Thai creative credits to an image circulating among Lisa's international audience. The story was about a celebrity costume, but also about how a designer's detailed work became the focal point of a widely shared visual production.

How the tail created its changing colors

UNKUNIYA's tail combined a dark foundation with several layers of color and texture. Greenish black scales supplied its main surface, with embroidery and shimmer catching the light. Orange and copper appeared beneath the black, giving the costume warmer accents within an otherwise cool palette.

Descriptions of the photographs also identified blue, emerald and teal tones. Together, those colors explain why the tail appeared richer than a flat black garment. The surface offered several shades for the lighting to catch, while the overlapping scale pattern gave the eye small details to follow along its length.

The fins supplied a different kind of detail. Both the tail and its sides were designed with flowing shapes that added depth around the scaled body. Their broad, leaflike outlines made the silhouette more elaborate than a simple tapered mermaid tail. The contrast between a densely decorated surface and loose, spreading edges helped define the creature.

Wutthichai's contribution was therefore central to the character's shape, rather than a small accessory within it. Nanist's role as the stylist leading the costume team connected that garment with the rest of the appearance. The credited collaboration placed costume design and styling alongside the makeup work that made Lisa's human features look unfamiliar.

Makeup carried the transformation beyond the costume

Lisa's makeup used a pearly sheen across darkened skin, creating a reflective finish that echoed the shimmer of the scales. Bright blue contact lenses became a strong point of contrast against the darker colors around her eyes and face. Long black hair, styled to look wet, continued the underwater appearance.

Blue and black scale patterns extended across her arms, with darker detailing around the hands and long nails shaped like claws. These repeated textures connected exposed skin with the tail. Instead of stopping at the edge of the clothing, the design continued across the body.

Additional details included metallic silver lips and finlike prosthetics around the ears. Prosthetics are pieces attached to the body to change its shape, a technique often used in film makeup. Here, they helped turn familiar features into parts of an imagined sea creature.

The crown introduced a harder, more structured outline above the flowing hair and fins. Its pointed black form and reflective crystals framed Lisa's face, while the fangs gave the character an openly threatening feature. The combination explained the Dark Siren concept through visible choices: an aquatic figure with both beauty and menace.

Water and glass became part of the image

Lisa posed in water and around a large glass tank, extending the aquatic theme into the setting. Some descriptions placed her inside the tank, while others highlighted poses on top of it. The photographs used both the water and the glass structure to present the full costume.

The setting mattered because much of the design depended on surface and shape. Water complemented the wet appearance of the hair and skin, while the tank provided a setting in which the long tail could remain prominent. The photographs gave viewers more to inspect than a close view of the makeup.

The session was described as Majestic Dark Siren, a name that matched its crown, elaborate fins and theatrical presentation. The character combined a mermaid's tail with the dangerous appeal associated with sirens in popular fantasy. Lisa's version used that familiar idea as a visual theme rather than recreating an ordinary sea creature.

The production budget, preparation time and full list of makers have not been disclosed. The publicly identified credits name Wutthichai, UNKUNIYA and Nanist, while the finished images show how costume, makeup, accessories and setting worked together.

More than 2.1 million likes in six hours

Lisa shared the Halloween photographs through her Instagram account, @lalalalisa_m, on October 31. The images also circulated through LLOUD, accompanied by a short caption that introduced the character.

The caption accompanying the photographs shared through LLOUD read:

Siren's calling...

The post's reported total of more than 2.1 million likes after six hours gives a precise measure of its early reach. Spread evenly across that period, the figure would amount to more than 350,000 likes an hour. The actual pace would have varied as people encountered and shared the photographs.

Comments focused on the scale of the transformation and the cinematic appearance of the costume. English comments from overseas fans were prominent, showing how the images traveled beyond Lisa's Thai audience. The photographs gave viewers an immediately recognizable fantasy subject while leaving enough detail to reward a closer look.

The look was also selected for a roundup of standout celebrity Halloween costumes for 2026. That recognition extended its circulation beyond Lisa's own posts, although the most concrete measure of the initial response remained the reported Instagram count.

A different direction from her earlier Halloween characters

Lisa's 2026 costume followed earlier Halloween transformations with distinct visual identities. In 2021, she dressed as Younghee, the doll from Squid Game. That character relies on a familiar face, hairstyle and outfit that audiences can recognize quickly.

Her 2025 appearance drew on the Golden Siren associated with Jibaro, an episode of the animated anthology Love, Death & Robots. The Dark Siren prompted comparisons with that earlier character because both used an elaborate, unsettling figure as the center of the image.

The 2026 look shifted attention toward a large mermaid tail, dark aquatic colors and textures extending across the skin. Its green, blue and black palette, with copper and orange underneath, gave it a different visual identity from the gold associated with the previous year's character.

The sequence shows how Lisa's Halloween appearances have moved between a recognizable television costume and more extensive fantasy transformations:

• 2021: Lisa appeared as Younghee from Squid Game.
• 2025: She adopted the Golden Siren look associated with Jibaro.
• October 31, 2026: She shared the Dark Siren photographs featuring the UNKUNIYA tail.
• Within six hours: The Halloween photographs reportedly passed 2.1 million Instagram likes.

The continuity lies in the attention to a complete character. In the latest photographs, the tail, scale patterns, crown, eyes and setting all supported the same aquatic theme.

BLACKPINK members chose contrasting fantasy worlds

Jisoo also shared a Halloween transformation on October 31, choosing Lucy from the anime Cyberpunk: Edgerunners. Her photographs used teal and pink lighting that echoed the character's appearance. Lisa's water setting and dark scales placed her in a very different fantasy world.

The contrast extended beyond the outfits. Jisoo's look depended on recognizable features from an established animated character, while Lisa's Dark Siren relied on a creature assembled through costume, body painting and theatrical scenery. Both presentations used lighting and accessories to carry the idea beyond clothing.

Jennie's photographs followed on November 1, showing her dressed as Suki, the street racer played by Devon Aoki in the 2003 film 2 Fast 2 Furious. Her purple top and hot pink leather chaps drew directly on the film character's wardrobe, and a red Honda supplied an automotive reference within the photographs.

Together, the appearances ranged from an aquatic creature to anime and a film about street racing. Lisa's stood apart through the scale of its physical transformation and the central role of a custom tail made by a Thai designer.

What the attention means for the credited makers

UNKUNIYA's name became attached to the part of the costume that viewers could most readily identify: the large, shimmering tail. The detailed credits gave audiences a route from Lisa's finished appearance to Wutthichai's design work and Nanist's coordination of the costume team.

The most distinctive craft details were also the ones that made the image work at different viewing sizes. The crown and tail established the character at a glance. A closer view revealed embroidered scales, hidden warm colors and the changing contours of the fins. Those layers allowed the design to function as both a dramatic silhouette and an object with intricate surface work.

Lisa's global audience brought those details to viewers far beyond the label's immediate following. The concrete result was visibility for a named Thai designer and stylist within a production attracting millions of reactions. The costume's success as an image depended on their work remaining visible, even within the heavy makeup, dark setting and elaborate accessories.
