Every garment is made in Portugal in close collaboration with trusted partners. We value traceability, human connection, and craft.
We collaborate with family-run and GOTS-certified factories that specialise in premium construction, responsible sourcing, and fair working conditions.
We visit our workshops regularly. We know the people behind our clothes - not just the company names.
Keeping production local reduces transportation, emissions, and enables us to produce thoughtfully rather than excessively.
Small runs. Traceable partnerships. Quality over volume.
