Unless you're wedded to Italian clothes, go to an American manufacturer for a "workhorse suit." Â In the middle to upper range that includes Brooks Bros., J. Press, Paul Stuart, and Hickey Freeman. You will need a strong cloth with some weight. Â The featherweight suits will not last. Â Do not get anything under 10 oz. Â As a general rule the English cloths are sturdier than the Italian ones. Â Also do not go for super fine cloths. Â Nothing over 100. Â An 80's will be fine. If you're buying off the rack, tell your salesman that you want a workhorse and a "suit that will wear like iron." Â If you have a good salesman and good shop, you'll find these in your price range. Good luck.
I think an 80's might be a little too austere. Assuming your job does not involve physical labor or extensive travel, anything up to 120s or 130s should be fine. Also, I don't know why a workhouse suit necessarily equates to American Trad styling. If you are looking to spend in the $800-1200 range, I would go with Chan since you can pick out an appropriate fabric and choose the cut and styling you prefer.
