It’s no secret that Grechen of GrechensCloset.com is a friend to the savvy shopper. If you frequent sites like RetailMeNot.com or ReesyCakes.com, you’ve probably seen her name as a code to get you 15 or 20 or 25 percent off an online purchase at some of your favorite fashion etailers.

But for a few months now, Grechen has started to turn her attention to the eco-issues that are near and dear to our hearts. It started with a list of online shopping sites that stock ethical fashion, and this past week the idea blossomed into GreenGrechen.com, a new blog that’s on our must-read list.

It also helps that Grechen has fabulous taste. Her list of 10 eco-pieces for fall? We want every last one of them. And as always, she leaves you with a cornucopia of codes to save you some money on your newest and greenest must-have.
