They say diamonds are a girls best friend but concrete may be the next best thing. Cement has gone sartorial with Karen Konzuk's latest Konzuk collection. Like materials such as adobe and other dried earth materials, concrete and cement has an ancient history tracing back to Assyrian, Babylonian, and Roman societies. Today, concrete has been the 'next big thing' in sustainable architecture for some time. And now its jumped to fashion and the results are rock solid. Konzuk's latest collection also features some great geometric designs. Best of all, Konzuk has pieces for both women and men.
