H&M's Conscious Collection may be just an annual event but according to the brand's head of sustainability, Catarina Midby, it's part of a much bigger picture and a drive towards a more sustainable future.

The Swedish retail clothing company launched the Conscious Collection two years ago. Since then, the range made entirely of sustainable materials such as organic cotton, recycled polyester, recycled polymade and Tencel, has been gathering momentum. Having started out with 30 pieces, it's now doubled in size, with an additional 20-piece exclusive line of super high end suits and dresses.
