One of the most common things you will hear about green living is that the little changes can make all the difference, such as switching your light bulbs or learning to compost. This simple and direct concept can easily be applied to eco-fashion as well, all at an affordable price.

Sustainable underwear is a branch of the green style market that is still developing, but there are a few companies that have been around since before being green became "trendy." One of them is bgreen. Based in Southern California, bgreen has been family-owned for three generations. Before you worry about what your jeans or sweaters are made out of, start with the first thing you put on - undies.

"We strive for performance and endurance. Simply put, each of our garments is built to last. Our designs are simple and bold, yet soft and sexy. Our embellishments add a playful, curious and youthful feel to our garments. We support local communities, fair trade and environmental preservation. We exclusively use certified organic cotton and low-impact dyes to make our fabric. We believe our planet earth is the only home we have. It is everyone’s responsibility to contribute everything they can to protect and preserve our delicate planet for this generation and many more to come," says the company's website, which also provides images of their sweatshop-free California factory. Men's and women's intimatewear are the most popular of their creations, though bgreen is now also making activewear for both genders as well.

Within their intimates line, colors are very limited, with most items available in white, natural, and black. For men, they offer three styles of underwear: tank tops, crew neck and v-neck tees,pj shorts and pants, and a thermal top and pant. As one might expect, the women's line has more options, including nine styles of underwear (three with lace), a bra top, two camisoles (one with lace), tank top, sleep dress, two styles of lounge pants, two different length leggings (one with lace), short sleeve and long sleeve tees, and a thermal top and pant. Reasonable prices make it all the easier to start replacing your older, tattered undergarments with healthier, organic cotton versions. Men's and women's undies range from $9-$16, and basic tops and tanks run from $16-25. Within their athletic collection, prices are still within everyone's reach: pants range from $30-$52, and tops and jackets are $25-$57.

Via the company's wholesale page, you can request a list of local retail stores that carry their items. If you are a fan of shopping online, check out the bgreen items available at LotusOrganics.com and OrganicSelections.com (men and women).
