a couple of times per month only?

Or are you looking for a business type suit that will look appropriate in a business setting?

For most people, I think the answer can be the same, but there are certain jobs/positions where you probably want to step it up a notch.

I like Burlington Coat Factory. You can get quality suits for a good discount. Even with the tailoring it probably needs, the pricing is probably well below Men's Wearhouse.
