You've hit your local H&M for a bargain buy, but how about one that promotes a healthy planet? After a successful spring launch, H&M is expanding its organic cotton line to include dresses, jumpers, and undies. We're most excited about what lies beneath. This adorable gray-and-white-trim bra and hipster brief set shows that you don't always have to advertise to others just how green you are. (Sometimes it's nice to keep a secret to yourself.) Gray bra and hipster brief, $12.90 and $7.90, available at H&M stores nationwide.
