I love design companies with a great aesthetic and an equally great design philosophy, like Keep & Share (which I discovered via Karin). I think it's helpful for designers to have a creative mission statement or design philosophy/manifesto so that every piece of work they introduce is charged with their ideals and fulfills their vision and goals. (Though there are plenty of folks out there just looking to jump on bandwagons and turn a quick buck, being a trend-chaser is hardly a philosophy!)
Keep & Share is a luxury knitwear label out of the UK. Here's an excerpt from their philosophy that I particularly enjoy, which talks about consumption and disposability:
"True to our name, we create quality pieces that will transcend short-lived trends and age gracefully; versatile products that can be worn in different ways and by different people over their lifetimes."
My favorite piece is this apron!
And I like that they use their scraps to make other products like these cushions. Nothing goes to waste.
