Green fashionistas can look forward to spring as H&M is set to unveil a fashion range made from organic cotton, recycled polyester and Tencel, a biodegradable fabric made from wood pulp cellulose.

The Conscious Collection will go on sale in all H&M stores from 14 April, featuring menswear, womenswear and children’s clothes “inspired by different shades of white”.

Customers will be able to choose from blouses, tunics, T-shirts, dresses, skirts, blazers and trousers made from organic linen and polyester recycled from PET bottles and textile waste.

H&M has been selling clothes containing organic cotton since 2004 and, as well as aiming to increase its use 50 per cent every year until 2013, is also looking to deliver a wider variety of green textiles.

“It’s not just about organic cotton any more; the possibilities for creating a complete fashion statement with eco-smarter materials are huge now. By designing recurring Conscious Collections we have the opportunity to show in a variety of ways what is possible using more sustainable fabrics,” said Ann-Sofie Johansson, H&M’s head of design.

The Swedish firm ran into trouble with environmentalists last year when it was caught throwing out unsold clothes. In the fallout, H&M promised to donate any products it did not sell to charity and last month released its Waste line, made completely of leftover pieces from a Lanvin collection.

H&M is part of a growing trend among fashion retailers to produce more environmentally sustainable clothes and the announcement comes just days ahead of the launch of London Fashion Week, where the Estethica show is expected to present the latest in green designers.
