We LOVE Stella McCartney. Not just because she and her designs are incredibly stylish, incredibly gorgeous and incredibly fun (see above), but because they are incredibly sustainable, too. McCartney knows how to play around, sending Cara and co down the catwalk shining brighter smiles and bolder dance moves than Paris Fashion Week has seen before. But she also knows how to make her brand as ethical as it is fun-loving. This season, all the wood used in her accessories (such as the shoes seen on the catwalk above), is FSC Certified, emphasising the brand's commitment to responsible forest management. So we suggest you go out, buy some of those gorgeous items and do your bit to keep the world's forests as beautiful and hospitable as they are today. After all, every little helps...
