Sustainability At Sostter - Not a destination. A direction.
Sustainability is not something we've perfected — and we'd be rather suspicious of anyone who claimed they had. It's a journey, and one we take seriously. At Sostter, every brand on the platform has been individually reviewed. We look for genuine commitment, not greenwash — real certifications, honest supply chains, and makers who care about what happens after the sale.
Here's what we look for.
Certified Organic & Natural Materials
We feature textiles and fabrics certified by GOTS (Global Organic Textile Standard) and OEKO-TEX® — meaning materials are responsibly sourced and free from harmful chemicals. If a brand makes that claim, we check it.
Recycled & Upcycled
Our sustainable brands integrate reclaimed fabrics, recycled plastics and repurposed materials into their designs — minimising waste and extending the life of valuable resources. Browse our resell, upcycled & vintage collection for more.
Ethical Production & Fair Trade
We support brands that uphold fair wages, safe working conditions and ethical labour practices. Many partners hold Fair Trade and Ethical Trade Initiative certifications — because how something is made matters as much as what it is.
Low-Impact & Non-Toxic Dyes
We highlight products using natural, plant-based or non-toxic dyes — reducing the environmental impact of traditional dyeing processes without compromising on colour or quality.
Sustainably Sourced Materials & Vegan Alternatives
Our home and fashion collections feature FSC-certified wood, responsibly sourced natural materials and innovative cruelty-free leather alternatives.
Zero-Waste & Circular Design
Many of our brands follow zero-waste principles — upcycled materials, minimal excess production, circular design models. Things made to last, not to be replaced.
Cruelty-Free & Vegan
We partner with PETA-certified and Cruelty-Free International brands that don't test on animals or use animal-derived ingredients.
Responsible Packaging
Many of our products arrive in biodegradable, recyclable or reusable packaging. Small decisions that add up.
Working Towards A More Responsible Future
We don't have all the answers. Nobody does. But we're asking the right questions — continuously reviewing our partners and products against evolving sustainability standards and ethical sourcing practices.
Every purchase is a small vote for the kind of world you'd like to live in. Whether you're looking for organic clothing, responsibly made accessories or sustainable homeware — our carefully curated edit lets you shop with confidence.
We're always discovering new brands pushing the boundaries of ethical and sustainable design. Our sustainable edit grows carefully and deliberately — we'd rather have fewer brands we truly believe in than a long list we don't.
