LOL, yes, I get what you mean.
I actually wished I had a black suit to wear with it today. First time I've thought that!
Other options apart from that and the ones mentioned by Monkeyface above, that I think might work: tan or tobacco linen suit, possible mid-blue blazer in a similar sort of fabric. Or mid slim grey trousers and a black leather jacket perhaps. I've been meaning to get one...
ooh... now this idea I Iike!!
You know, the more I think about it, the more I think I was unconsciously chanelling some kind of Blade Runner-esque vibe by pairing it with a suit. I do love that movie. Was there something similar in Gattaca too? Can't remember.
Anyway, now this theme has been made conscious to me, through your and AAS's posts, I think I have some ideas of how to deploy it in a more directed way within that theme next time.
I think Gattaca had spearpoint collars, but a nehru collar would definitely fit with the spirit of that movie.
