The Live Frankly seal of approval:
These are really good brands, doing good things. To be included in this list, each brand has been given the Live Frankly seal of approval. We are not a certification, but we talk with every brand and ask them to complete a comprehensive questionnaire about their ethical standards before we feature them. No brand is perfect – we’re all operating in an imperfect world – but only purpose-driven brands that are working to change things for the better feature on Live Frankly.
We ask that workers’ rights and pay are ensured across the supply chain, that brands use sustainable materials and want to know about their governance structures. This means you can be confident these brands are some of the most ethical and sustainable around. If you have any questions, please get in touch.
Final note: Free returns really hit small brands hard because they’re not actually free. It takes time to pack and unpack clothes and costs money to send packages back. Did you know that sometimes big brands send your returns straight to landfill? So, help them out. Try only to order what you really want, and return items when absolutely necessary.
