I've no serviceable dinner suit, and probably no time for my tailor to make one up. I don't want to buy a RTW traditional dinner suit, as I know I'd regret it. What am I to do? Any ideas for something maybe unstructured and paired down that could serve as a dinner suit equivalent? I'm looking for the evening appropriate equivalent of the early unstructured Armani suits, say. The context isn't overly traditionalist anyhow. Thanks in advance.
