When looking around for an off-the-rack suit or a tailored suit, you may often see the cheap suits come with a textile label listing some kind of micro fabric or in the best case scenario mixed wool. This means that only a certain percentage of the fabric is made from wool while the rest of the fabric is from different types of polyester material. Then you have the branded and non-branded suits, throwing around Super Wool numbers such as Super Wool 150S or “Tropical Wool” etc. And to add further confusion, some fabric brand suppliers offer worsted wool. So, what are the differences among these materials and why do some cost more than others?
