From the first sketch to the final stitch, every stage of the creative process goes through our hands. We design, draft patterns, and craft each piece in our atelier in Barcelona, entirely by hand and in very limited series.

This philosophy also guides our bespoke work: we collaborate closely with each client, or each boutique, to transform ideas into unique pieces, made with precision and dedication. Every seam reflects our passion for excellence and the value of craftsmanship.

Each Sienna & Gaia piece is a statement of style and personality. We design pieces with soul, created to accompany special moments and stand the test of time. Our goal is not to follow fleeting trends, but to offer timeless luxury that celebrates the individuality of every woman.

We believe fashion goes beyond clothing — it is a form of expression. That’s why every collection, every design, and every bespoke project is created with intention, carefully crafted so that your garment becomes part of your story.

Quality is the foundation of everything we do. That’s why we work exclusively with European suppliers who share our values of savoir-faire, sustainability, and attention to detail. Every fabric we choose, every finish, and every button meets the highest standards.

Our production is thoughtful and deliberately limited, ensuring the exclusivity of each design. This same philosophy guides our collaborations with selected boutiques in Europe: pieces conceived to stand out, bearing the distinctive mark of craftsmanship and contemporary luxury.
