I don't recall exactly the price of the first run of Work Trousers but I know they were at least $220, and I think closer to $250. So, even if it was the former, the price increase is not outrageous, though it's not trivial either. The fabric is expensive, I know that. My pair were a sample, and I bought them from Karl for a good deal, but still a price closer to his standard denim jeans.
Mine are nearly identical to a final pair, save a few minor finishing details--no screen printing on pocket bags, for example--and the fact that they are cut a little slimmer through the thigh and leg. Honestly, that's my only complaint: I could use a touch more room in the thigh. Other than that, these are some of my favorite pants, maybe ever.
