Q: What materials contain organic cotton? A: Organic cotton is the most popular type of organic fabric. It's also used in personal care items like sanitary products -- cotton swabs and baby diapers -- as well as home goods like sheets, towels and stationery.

In our imaginations, organic clothing usually isn't very fashionable. It reminds us of Birkenstocks, shapeless tunics and burlaplike textures -- tie-dye optional. But our imaginations are stuck in the 1970s. Organic and alternative fibers have come a long way since then.

Organic clothing is made of all-natural, non-synthetic materials and is a part of the organic agriculture movement. This movement emphasizes farming and processing that work with nature and help minimize air, soil and water pollution. Organic clothing materials come from plants that have not been radiated, genetically modified or treated with synthetic or chemical pesticides. Any product labeled organic, whether it's a T-shirt or an apple, has to meet national standards set up by the United S­tates Department of Agriculture (USDA).
