Ethical women's bottoms

Meet our women's ethical clothing range for the lower half!

We have selected pioneering brands making their way to positive change in the ethical fashion industry. Here at Know the Origin, you can find all sustainable fashion bottoms for active women in one place (no need to search 1 million websites before finding the perfect piece!)

From organic cotton to bamboo, fair trade to recycled textiles made from plastic bottles, you won't find as many beautiful brands than right here using eco friendly natural fibres, certified organic cotton, and recycled plastics in such amazing ways.

From sizes xs for those slim and fabulous to xxl for the gorgeous plus sizes, you will find bottoms to suit all bottoms. Ethical brands manufacturing right here in the UK, to sunny filled rooms of designers in Australia and all over the world, these stylish and ethical women's bottoms, leggings, shorts and more will support you at the gym all the way through to brunch. From relaxed fit, to figure hugging, booty lifting goodness, you won't be seeing any see-through leggings in our neck of the woods, so you can squat, jump, and do the school run knowing we got you covered (literally).

We're here to make sustainable living, easy and luxurious. Buying from us, you're helping minimise waste, water usage, helping uk brands as well as feeding a healthy supply chain, while supporting sustainable fashion and slowing down the toxic fast fashion industry.
