Most suit fabrics can be considered to be eco-friendly due to their organic origin. With the likes of linen, Viscose and cotton coming from plant-based origins and the likes of wool and silk from animals. However, the argument on whether these fabrics are environmentally friendly lies in the farming practices used. The likes of cotton require a heavy amount of land, pesticides and thousands of gallons of water to grow and do a lot more harm to the environment than most people realise. However it is not all bad - there are sustainably grown suit fabrics such as linen which is biodegradable and requires less land and pesticide to grow, but will often come with an eye-watering price tag. The argument on whether suit fabrics are eco-friendly is based entirely on the type of fabric you decide to go with to make your garments.
