The dress code in my office department is dress trouser and shirt, and if needed, we 'go up' to a sport coat. In all the years I have never needed to wear a suit. I am looking to purchase (or have made) a few pairs of dress trousers with the stipulation that the material both qualifies for business casual wear and is also very durable. In short it should neither be denim, nor something up there in the super 130s etc (Unless someone knows that these are the really durable materials). I would love suggestions on what brands, and cloth, that members have found that are hard wearing but also qualify as business casual. Summer and winter materials. I'd like to wear these for a few years, and not have to buy every season. Example of a brand: is the Epaulet Walt trouser? Example of possible material: Moleskin? Thanks!
