<a href="http://www.selfridges.com/GB/en/cat/ theory" style="text-decoration: none"><font color="black"><b>Theory</b></font></a> knows that staples don&#39;t need to be flashy; this Lanai wool <b>blazer</b> focuses on a precise cut, stunning fabric and a simple line to make its presence known. The slightly cropped design has been left open at the front to give it a fresh silhouette, and comes fully lined for a comfortable wear. Put a modern spin on the suit by wearing with the matching trousers or mix it up with jeans and a tee.
