So glamorous, perfect dressed up or down.

The Dubois Bias Gown in Fossil exudes understated elegance with a fluid, feminine edge. Cut on the bias from lustrous Naia™ acetate, this maxi silhouette skims the body with effortless grace, draping softly over every curve. A delicate scoop neckline meets an across-hip panel line, adding subtle structure before falling into a gently flared hem for beautiful movement. Timeless yet modern, this piece is perfect for moments that call for quiet sophistication.
100% Naia™ Acetate

Fit: I have included a US dress size size chart in inches as well as Spell's size chart (in cm). I found this piece to fit a little on the generous side, stick with your usual for more drape or size down for a closer, body skimming fit.

So, what is Naia™?


Naia™ is a cellulose acetate yarn made from responsibly sourced wood pulp. It’s silky to the touch, breathable on the skin, and completely biodegradable—without the water-intensive burden of cotton or the chemical heaviness of traditional viscose. It offers the luxury of drape and structure, without compromise.
But what truly sets Naia™ apart is its transparent, traceable, and safe production process. Every fibre is OEKO-TEX® 100 Class I certified, ensuring it’s gentle enough for the most sensitive skin—and kinder to our planet. Compared to conventional materials, Naia™ uses significantly less water and energy, reducing its carbon footprint at every stage.
