Natural fibres, vegan, made to last

Our pieces are made in organic and natural fibres — cotton, linen, lotus, hemp, lyocell — or in deadstock fabric given a second life. Every piece is vegan, and we work with local seamstresses who are paid fairly.

How we make it

Studio in Sesimbra

We are Raquel and Sofia, twin sisters. We design, cut and sew between the beach and the mountain, surrounded by fabric samples, books and cactus. Visits are welcome, by appointment.
