One of the rules of green clothing is to use second hand clothing. This is because clothing that is already made does not use additional resources. Reused clothing is actually the greenest clothing there is, which can seem counterintuitive to some. After reused clothing, clothing that is made from recycled materials is the greenest. In fact, clothing made from recycled materials is often (but not always) greener than clothing made from organically grown materials. The processing needed to turn the organic fibers into cloth uses large amounts of resources.
Recycled Clothing from Man-made Materials
It seems like a contradiction to look for clothing made from man-made materials; so many people know how damaging they can be. However, because of their sturdiness and their specific qualities, man-made materials are often recycled into other things. You may actually end up wearing clothing from man-made materials that is environmentally friendly.
You should consider the processes that clothing has gone through in order to become a wearable product. This is important, since the process that the clothing undergoes can have more of an impact on the environment than anything else. Also, consider that making something new, even if it is made from organic cotton, can be harmful to the environment when compared with something reused or recycled. These types of reused and recycled items, since they have already been produced, aren't usually using additional resources.
However, if you cannot find something suitable from recycled, man-made materials or something second hand, it is a good idea to look for organically grown materials. One of the worst things that you can get -- at least from an environmental standpoint -- is traditionally grown cotton. The pesticides, large amounts of water and other issues associated with regular cotton make it very resource-intensive.
Even though it may seem odd, consider clothing made from recycled, man-made materials, which translates into fewer things going to your local landfill.
