PREVIEW

Hundreds of meters of bright red fabrics are laid out in neat rows across a field in Narsingdi, Bangladesh during winter. Known as ''Lal Shalu'' to the locals, the long red cloths are set out to dry under the hot sun, having been dyed with bright red color. The use of sunlight to dry out the fabrics reduces production costs as it is cheaper and more sustainable. The eco-friendly drying method spans an area equal to 5 football fields and takes up to 6 hours to complete after being placed by workers at sunrise. Once a strip has been properly dried, workers fold it up and replace it with another, newly dyed stretch. The clothes, which sell for less than 10 GBP, are used in garment factories making women's dresses.
