I've said it before, and I'll say it over and over again -- looking good and feeling good really do go hand in hand. I don't mean that dressing in cute clothes will make you happy (although I promise it won't hurt). Rather, if you feel good -- healthy, happy, optimistic -- it'll show.

I always feel better when my purchases support my beliefs, so when I heard that Fila had teamed up with AmericanForests.org, I was intrigued. Then, I found that not only had Fila made a one-year commitment with the nation's oldest and most respected non-profit dedicated to tree planting in the U.S. and globally, but they were also using eco-conscious fabrics in their Women's Personal Performance line. Sold!

The brand has incorporated the use of sustainable and recycled fibers, like soy, bamboo and recycled Polyester into their women's line. Initially launched in 2008, the line has proven that fashion, function and eco-friendliness can go hand in hand (uh, in hand). Don't even try to tell me you're not into the Fila Twist Back Yoga Tank ($58), or the Flower Sleeveless Muscle Tank ($50).

And yes, I realize that $50 for a top is more than you'd pay at, say, Target. And I know that's hard right now. But, consider this -- would you rather have one piece that supports a company that's incorporating sustainable practices and donating money to get more trees planted, or three pieces that don't?
