6 of the best sustainable clothing brands in the UK in 2021

Latest News

Fast fashion is notorious for its flimsy ethics. But that doesn’t mean sustainable clothing can’t be affordable, and here are the UK’s best brands to prove that.

Yes, fast fashion is bad. Between the human rights abuse cases and the animal testing scenarios, you’d be forgiven for forgetting about the fashion industry’s environmental impact with the toxic chemicals in its production processes and polluting supply chain practices.

Buying sustainable is always better, of course. But one major criticism of eco-friendly clothing brands is that they’re on the pricier side. While sustainability can be costly, as can be seen in the eco-friendly arms of larger brands like Stella McCartney, it doesn’t always have to, and here are some of the best affordable sustainable clothing brands in the UK that prove that.

Finf out whether Primark deserves its ethical fast fashion question mark.

A post shared by BIBICO (@bibico_clothing)

Bibico came about when designer Snow became disillusioned with the fast fashion industry after years of designing for high street brands. The company emphasises its disregard of cheap synthetic materials, instead relying on natural ingredients to make its fabrics and garments. It also recognises the environmental impact of the fashion industry, especially with the number of toxic chemicals pumped out, and therefore has introduced an organic cotton collection.

It produces high-quality sustainable women’s clothing in two Indian fairtrade women’s cooperative factories. But the best part about it is how affordable it is, especially given the timelessness of its range. Trousers start from £69, and it also offers accessories like scarves, slippers, socks, beanies and gloves.

“Modern basics”, “clean lines” and “easy silhouettes” is how Baserange describes itself. The brand develops high-quality fabrics and textile from natural fibres and recycled materials, and believes committing to clean fashion would have a positive environmental impact.

The basics it mentions include sustainable lines of underwear, swimwear and loungewear. The brand only uses natural and biodegradable ingredients like cotton, bamboo, wool and linen (which is derived from the highly sustainable flax plant). Its underwear line is priced from £25 and tops start at £50. It also manufactures socks, bottoms, pants, dresses, jumpsuits and accessories like scarves and face masks.
