① O0u
O0u made its debut at Rakuten Fashion Week Tokyo this season, unveiling its 2025 Spring/Summer collection at the Telecom Center Building in Koto Ward, Tokyo. The collection was themed “LIVING IN A CIRCULAR WORLD,” focusing on natural beauty and sustainability. Through the concept of “circle = circulation,” it depicted a harmonious flow between the Earth, resources, culture, and our daily lives.
The brand advocates a lifestyle centered on “a new normal” and “a new cool.” Each item in the collection incorporates materials like recycled polyester, natural fabrics, and recycled resources, reflecting the brand’s philosophy of embracing both individuality and environmental responsibility. This collection embodies O0u’s clear vision of “circulation” and “harmony” through the lens of fashion.
The Elegance of Harmony Through Soft Design
The core of the collection lies in its soft curves and circular motifs, which symbolize tranquility and harmony, creating a sense of cohesion throughout the entire collection. The color palette ranges from clean off-white to gentle pastel shades and timeless classic hues, offering a variety of expressions. These colors beautifully reflect the delicate softness and inherent strength of nature.
Furthermore, flowing drapes, three-dimensional gathers, and delicate ruffle details add a sense of lightness and movement to the styling. Nude-colored formal jackets and tops are layered with sheer organza, lending an airy texture and a refined elegance to the pieces.
The rounded leather bags, carried by the models as if cradled, exude an elegance perfectly suited for everyday use. Additionally, the cylindrical bags are adorned with large plush charms, injecting a playful touch that adds a distinctive presence to the accessories.

Reconstructing Timeless Elegance
These timeless staples, beloved across generations, have been revitalized by O0u’s vision of “circulation” and “harmony,” breathing new life into them as contemporary everyday wear. At the same time, this represents the brand’s bold endeavor to redefine modern elegance through the use of sustainable materials and sophisticated design.
② Seivson
Taiwanese designer Tzu Chin Shen, the creative force behind SEIVSON, unveiled the brand’s 2025 Spring/Summer collection under the theme “TRACE: Traces.” This thought-provoking collection delves deep into societal issues, symbolically exploring the “traces” left on women’s bodies by the contradictions and distortions of truth that permeate modern society.
Layered Designs Depicting “Traces”
The collection opens with body-conscious pieces that evoke the image of torn tape wrapped around the body, setting an audacious and striking tone. From there, SEIVSON showcases its signature approach of deconstruction and reconstruction, with standout designs including jackets featuring inverted structures, outerwear that seamlessly fuses contrasting patterns, and flowing silhouettes imbued with dramatic volume.
These designs not only accentuate the natural contours of the female body but also skillfully incorporate layered fabrics and distressed textures to visually narrate the theme of “traces.”
This collection introduced new materials such as Kyoto’s Nishijin-ori textiles and eco-friendly fabrics, in addition to SEIVSON’s traditional choices. Items featuring deep distressing were further enhanced with hand-finished touches, infusing each piece with a distinctive texture and a sense of vitality.
As a result, the garments transcend mere fashion items, emerging as individual works of art, each with a unique presence and story to tell.

A Philosophical Approach Beyond “Wounds and Healing”
Through its 2025 Spring/Summer collection, SEIVSON confronts the contradictions of modern society, transforming their “traces” into a powerful creative expression. By addressing universal themes of wounds, healing, and evolution, the brand captures contemporary societal challenges and translates them into refined, sophisticated designs. This approach reflects SEIVSON’s deeply rooted philosophy and unwavering conviction.
In a world where beauty and contradiction intertwine, this collection continues to explore the potential of fashion as a medium. It invites viewers to engage in profound reflection while opening new avenues for dialogue with society.
③ MURRAL
This season, MURRAL held its runway show at the lobby floor of POLA Aoyama Building, presenting a collection under the theme “SEEM.” This concept, which can be interpreted as “appearing to be” or “seeming to be,” embodies a profound inquiry into the nature of beauty and the diverse perspectives through which it is perceived. Having long placed flowers at the core of its creative expression, MURRAL revisited the essence of beauty, exploring the delicate elegance and peculiar strangeness hidden within flowers in this thought-provoking collection.
Inspired by a Monochrome Botanical Atlas
The collection draws inspiration from Urformen der Kunst (Art Forms in Nature), a botanical atlas published in 1928 by German botanist and photographer Karl Blossfeldt. This compilation of monochrome photographs highlights intricate details of plants that often escape the naked eye, capturing a duality of beauty: both graceful and strange. Designers Yusuke Muramatsu and Ayumi Sekiguchi embraced this duality, weaving it into the theme “SEEM.” The marble-like prints and abstract botanical motifs featured in the collection are directly inspired by the artistic essence of Blossfeldt’s groundbreaking work.
Diverse Materials and the Interpretation of “SEEM”
The collection masterfully embodies the theme of “seeming” with pieces like satin fabrics that mimic the texture of leather and beadwork that resembles entwined vines. By transforming materials and shapes that appear to be something else into quintessentially MURRAL creations, each item achieves a balance of visual intrigue and philosophical depth.
Intricate embroidery and prints further enhance the collection, skillfully expressing the symbolic nature and unconscious beauty of flowers. These details act as a mirror reflecting the complexity and allure of nature itself, oscillating between light and shadow, elegance and strangeness, symmetry and distortion. The result is a collection that captures the multifaceted essence of the natural world with remarkable artistry.
In the latter half of the collection, a series of radiant mint green looks took center stage, particularly captivating with a long skirt and a long dress adorned with gold, violet, and white accents. These mint green ensembles seamlessly fused vibrancy with tranquility, embodying abstract botanical patterns that exuded both grace and serenity. This stunning finale left a lasting impression, encapsulating the collection’s harmonious interplay of elegance and stillness.

The Fusion of Visual Beauty and Philosophical Inquiry
MURRAL’s 2025 Spring/Summer collection transcended the boundaries of fashion, offering a profound artistic exploration that sparked inspiration on many levels. By seamlessly merging visual beauty with philosophical inquiry, the collection not only rediscovered the essence of beauty but also challenged and redefined our own perceptions of what beauty truly means.
