Traje dos Açores, the vibrant traditional costume of Portugal's Azores islands, embodies centuries of cultural identity with its distinctive colors, intricate embroidery, and symbolic motifs. As global demand grows for authentic cultural attire, mass production has introduced critical quality risks: toxic dyes, structural weaknesses, and cultural misrepresentation. At CZ-Quality, we implement specialized protocols to safeguard both wearer safety and heritage authenticity.
