New user, long time lurker.
So I have to ask? What's really wrong with black trousers? It seems to be really hated around these parts. I get that if you just wear a white shirt, you'll look like the waiter. But for my office, a suit would be too formal. So I usually do a slim black trouser/patterned shirt/knit tie combo, and works reasonably well. I just find khakis to look so informal and casual, and have yet to find a pair that seem appropriate.
Or am I going to get lectured at for going against the groupthink?
