Worsted wool is the most common material for suits, and is by far the best choice for a first suit. You might come across a wool suit that is advertised as a "high-twist," 100, or Super 110. These are not car races. This just means that the suit is made of a worsted wool yarn that has been twisted more often than the usual 60-80 twist fabrics. This makes it a finer cloth of a somewhat lighter weight. Such suits would be perfectly fine, therefore, for spring, summer, and fall, but might not carry you through the winter. In this case, we urge you to consider the local climate when making purchasing decisions.

The mid-weights are best overall, especially with the usual "air-conditioned-car-ride-into-the-air-conditioned-office" venture that most people have in summer. And if you will be visiting a lot of clients or doing hefty traveling, you will need this kind of durable fabric which will stand up to the extra wear, but not be too hot.
