We designed the classic organic thong, with comfort as a priority, which for many ladies is not what they think of with usual thong styles. We gave them a mid-rise so you won't get a muffin top, and made them is a soft organic jersey with the tiniest bit of stretch (this helps with comfort too). 

The zero elastic on the legs is designed for a comfortable finish and feel on your silhouette, to avoid the dreaded indent some styles can give - due to the elastic finish.

We think they are classic, comfortable underwear that will become your new everyday favourites!

Details:

  • Fabric: 95% organic cotton jersey with 5% elastane
  • Comfortable fit with no elastic around legs
  • Fits true to size

      As a tiny brand, my business practices are so different—not just from large companies but even from other small businesses creating similar products.

      For me, sourcing fabrics and trims means purchasing overflow materials—what bigger brands have left behind. It’s not quite “deadstock,” but it’s close. Many lingerie supplies require minimum orders of 10,000 units, so I work with what’s available—often organic or recycled materials that others have already chosen. While this can feel a little restrictive, it’s also incredibly rewarding to reduce waste and give surplus materials a new life in my designs.

      What also makes me different is my hands-on approach. I’m not just designing; I’m involved in every aspect of my business. From choosing fabrics to perfecting fit, packing your orders, and even answering your emails, it’s all me! This level of personal connection means every piece you receive has been created with care, intention, and a commitment to sustainability.

      Unlike many SMEs, my focus is on creating small, thoughtful collections that reflect timeless design and avoid the cycle of fast fashion. I don’t follow trends—I create pieces that last, both in quality and style.

      Thank you for supporting me, Madonna, and my little brand, Eco Intimates. Your choice makes a huge difference, not just to me, but to the way we move towards a more ethical and sustainable fashion industry.

      Warmly,
      Madonna

      Our Makers

      I partner with a small group of home-based makers and small studios in Bali. I work closely with them from sampling through to production, ensuring consistency in fit and finish.

      • Small-batch production
      • Direct working relationships
      • Quality control oversight
      Sustainably Produced

      Each piece is handcrafted, not mass produced. The focus is longevity—quality materials and careful sewing designed to last.

      • Smaller production runs
      • Less overproduction
      • Flexible seasonal colour releases
      Sustainable Fabrics

      Natural fibres are central to Eco Intimates. Organic cotton jersey and stretch organic cotton (with minimal elastane for recovery) are sourced from OCS-certified suppliers using Oeko-Tex certified dyes.

      Designed in Australia

      All collections are designed by me in Northern NSW. Shapes are developed for comfort, function and everyday wear before being refined with my makers.

      Packaging

      Packaging is minimal and plastic-free wherever possible.

      • Cream tissue wrap
      • Compostable mailers from Better Packaging
      • No excess marketing inserts
      Journey to Better

      Sustainability is ongoing. I’m committed to improving materials, processes and transparency as the business grows, while keeping quality and ethics central to every decision.
