We are Nani and Andréia, two sisters born in Brazil and trained in fashion and footwear design. In 2021, we decided to turn our passion into a shared project: Sienna & Gaia, a fashion brand that brings together craftsmanship, exclusivity, and creativity in every piece.

From our atelier in Barcelona, we design and create unique garments, handcrafted with noble fabrics sourced from Europe. Each design is the result of a careful and meticulous process, where we combine traditional patternmaking, moulage techniques, and artisanal savoir-faire with a contemporary vision.

Our production is intentionally limited, because we believe that true luxury lies in exclusivity and in the value of the time devoted to every detail.

Sienna & Gaia is a brand created for women with strong personalities — independent, confident, and self-assured — who value quality, authenticity, and individual expression through fashion. Our purpose goes beyond dressing: we want to inspire other women to follow their dreams and build their own path, just like we did.
