PRODUCTION

Opaak partners with a leading Romanian production specialist renowned for expertise in lingerie, corsetry, swimwear, and light garments. With over 30 years of experience in contouring design, the female-led facility ranks among the top three in its field and operates under strict EU ethical, social, and environmental standards.

As a member of the Business Social Compliance Initiative (BSCI), it upholds high standards in craftsmanship, employee welfare, and workplace safety. In 2023, the company relocated to a new, state-of-the-art atelier in Cluj, further strengthening its commitment to technical excellence and responsible production.

Our creative team in Düsseldorf collaborates closely with the factory’s in-house pattern department through regular visits, fittings, prototyping, and rigorous quality control. This hands-on partnership ensures precision, transparency, and mindful craftsmanship at every stage.

For Opaak, true luxury lies in integrity, expertise, and intention - creating refined pieces with care for both the wearer and the people who make them.

MATERIALS

At Opaak, we prioritize ethical sourcing and sustainable supply chains. All materials are sourced from certified European partners - primarily in Italy, Germany, and France - ensuring transparency and traceability.

Our fabrics include regenerative and recycled materials, GOTS-certified organic cotton, and other eco-friendly, toxic-free textiles. We are continuously researching innovative solutions to offer a vegan, sustainable product range without compromising on design, quality, or performance.
