I think I could like it, but it would depend on the fabric. Almost-black, looks-like-they-came-from-a-suit trouser, no. But a slightly more textured, slightly lighter charcoal, yes. I should add, although...I'm not much for "rules" in general in the strictest sense. And there could be other reasons for the disdain of the navy odd trouser than what I have mentioned here, that don't extend to the charcoal trouser, so I'll wait for those who first began the navy trouser discussion in this thread to further justify their opposition to the navy trouser.
