Each source is averaged first, then sources are weighted by reliability: audits, lab tests and verified-buyer platforms count most, rating organisations and expert reviewers less, brand-run reviews and community opinion least. Review scores also weigh by how many reviews stand behind them, and anything older than three years fades.

Sourcing & ethics
Independent Portuguese brand founded in 2014 by Isabel Henriques da Silva and José Maria Refóios (also the founders of OFFICINA Lisboa). All production is in Portugal, in family factories in the north; the founders say they have worked with one main factory for over a decade. In 2023 Maisons Julien et Kelly Dassault (MJKD) made a seed investment. About 95% of sales are exports. It also has a vegan line that uses apple-based material. No third-party certifications found.
