3 days/wk for work, other days sport coat and slacks. Depending on the suit you can wear one for everything but physical work, sports and their overlaps (eg hiking, camping, fishing, etc etc.)-a more casual suit such as a tweed for the colder times, corduroy anytime, cotton or linen of various types for warmer climes, with or without a tie, appropriate casual shoes (loafer, boots, etc), with or without a sweater, vest etc. can adjust its look. This of course will depend on where you live-easier in a city, college town etc and your job,profession-law, medicine, teaching, sales, business rather than farmer, mechanic, etc. I think it is a great look and certainly marks the wearer in contradiction to the usually more casual (or even slovenly ) look mostly seen today. Give it a try-I'd go with a nice tan corduroy suit because it is so easy to dress up or down and the jacket easily passes as a sport coat if needed.
