Is the future of fashion fish skin? An article by Wired UK hypothesizes it

Until the nineteenth century, fish skin was used by Icelanders as a material to make shoes and durable accessories, nowadays, it is considered a valid ecological and luxurious alternative to classic leather. The advantages of this type of product? It is incredibly resistant, while light, it can be smooth, like cowhide, or, if you leave the scales, it can give a beautiful effect reminiscent of snakeskin. It is eco-sustainable because it consists of a by-product of the food industry destined to be discarded. For example, a ton of fillets produces about 40 kilograms of skin that is wasted.

It is less polluting since the tanning and dyeing processes used for fish are much less aggressive for the environment than those used for mammalian skins, which, as an article in Eluxe magazine points out, require strong chemicals responsible for the release of gasses such as hydrogen sulfide (an explosive, corrosive and flammable gas).

John Galliano, Prada, Christian Dior, Louis Vuitton, Salvatore Ferragamo, Nike (who is experimenting with the creation of perch leather running shoes) and many other big brands are trying to be sustainable and in so deciding to move towards alternative skins, also due to the lack of quality leather, less and less is available due to the high demand for expensive products in the material coming mainly from China and millennials.
