Sandblasted jeans are a look that denim makers are literally dying for…Levi's and H&M have agreed to stop using the sandblasting process on their denim products out of concern for the health of its workers overseas, reports Women's Wear Daily. The crystalline silica, which is used to give denim a beaten-in look, has been linked to worker deaths from silicosis, a fatal lung disease, according to the International Textile Garment & Leather Worker's Federation. According to the ITGLF, 40 garment workers who worked to sandblast clothing have died in Turkey between 2005 and 2009…ITGLF told WWD that the group is working to convince other fashion brands to stop exposing their workers in countries including China, Pakistan and Bangladesh to this dangerous process.
