Living Tissue Clothing
via Wired News: "The jacket is being grown inside a specially designed bioreactor that acts as a surrogate body." Creepy.. but only because we are unfamiliar with idea. As the article points out, we have no issues with peeling the skin off a previously-living animal and wearing it... this would provide a way of wearing the skin without needing to kill an animal. It isn't clear whether the clothing would be kept alive while you wore it, or it would be 'slaughtered' first.
