For Spring/Summer 2026, Her Royal Highness Princess Sirivannavari Nariratana Rajakanya takes us beneath the waves with “The Eternal Nautilus” — a breathtaking journey through the beauty, power, and mystery of the sea. The collection feels like a dream between reality and imagination, where fashion moves like water — sensual, fluid, and full of quiet strength.
Inspired by the spiral of the nautilus shell, the designs capture the rhythm of ocean life through swirling drapes, light layers, and fabrics that shimmer like sunlight on water. Sheer silks, floating chiffons, and crystal mesh create a sense of motion, while sporty cuts and urban details bring a modern, wearable balance.


The womenswear explores elegance in movement: short skirts built from layered ribbons, sailor-style dresses, soft harem pants, and fluid gowns that echo the sway of jellyfish. Each look feels alive — a blend of craft and contemporary ease. The color palette glows with oceanic tones: soft blue, coral orange, Thai indigo, pearlescent white, and hints of silver — all evoking the changing light beneath the sea.



Menswear channels the spirit of sailing, with relaxed tailoring, striped linen, and asymmetrical blazers adorned with embroidered seahorses and coral motifs. It’s refined yet effortless — the image of a man carried by the wind and sea.



What makes “The Eternal Nautilus” truly remarkable is its deep connection to Thai craftsmanship. The collection uses natural, sustainable textiles sourced from across the country — indigo-dyed fabrics from Sakon Nakhon, handwoven denim from Chiang Mai, and delicate crochet made by northern artisans. Every piece tells a story of tradition reimagined through innovation.
Accessories continue the oceanic tale: raffia and rope bags adorned with shells and crystals, conical heels in clear acrylic, and gold jewelry shaped like coral and clams. Even recycled fishing nets are transformed into new accessories, turning waste into beauty and echoing the designer’s ongoing work to protect Thailand’s marine life.
In “The Eternal Nautilus,” Princess Sirivannavari merges art, sustainability, and storytelling with effortless grace. The result is a collection that feels both timeless and modern — a love letter to the sea, and a celebration of strength, freedom, and the eternal dance of life beneath the waves.
