When looking at suits, jackets, trousers and overcoats these days, many made from pure worsted wool fabrics will likely boast a super number somewhere on the tags. You will find these numbers tend to start at 100 (you can actually go as low as a super , brands simply tend not to advertise the super number on anything lower than a super 100s), and going – in some rare cases – above 200. There is a misconception that a higher super number means higher quality; this is not the case! It simply corresponds to the fineness of the fabric.
