This summer, I visited Portugal for the first time and was captivated by its stunning landscapes, delicious cuisine, and rich cultural heritage. Beyond its natural beauty, Portugal also has a vibrant fashion scene.

Price Range: €34,10 — €147,56
Size Range: S — L
Conscious the Label is dedicated to creating timeless, high-quality swimwear, prioritising sustainability at every step. Each piece is designed using ECONYL®, a regenerated nylon fabric made from ocean waste such as discarded fishing nets, fabric scraps, and industrial plastics. This innovative material helps reduce waste and significantly lowers the global warming impact of nylon production by up to 80% compared to traditional methods. The ECONYL® yarn, sourced from Italy, ensures that Conscious swimwear is durable and environmentally friendly.
All of Conscious the Label’s swimwear is ethically sewn in their Lisbon atelier by a team of local seamstresses with over 40 years of experience. This local production approach allows the brand to maintain close involvement in the entire process, ensuring minimal waste and high-quality craftsmanship. The brand is committed to fair labour practices, ensuring all workers are treated ethically and paid above the minimum wage.
While the current fabric blend used in their swimwear includes 78% ECONYL® and 22% Elastane, making it not fully recyclable, Conscious the Label is actively working towards a future where their pieces can be recycled into new products. This vision aligns with their goal of achieving a circular production model, further contributing to reducing waste and environmental impact.
