Tan seersucker suit -- cloth and details choices

So I would like a tan cotton suit, and I do like seersucker. It wears its unavoidable wrinkles better than most other cotton, and in any case I'm intensely relaxed about wrinkles. But I'm not too keen on small-scale stripes in contrasting colours -- does any mill make tan-on-tan seersucker? The texture contrast is more than enough for me. I'm going to see my tailor sometime this week, but I suspect that his books won't have many seersucker choices (he's in Italy and quite old-fashioned in an Italian way). So if anyone knows a good source, I'm all ears. If someone has a good argument against self-striped seersucker I'm also open to be converted to another choice of material -- but please don't say linen, as I've got enough of the stuff. I've got a lightweight pair of wool gabardine trousers in progress and I like that material very much (I think it's Zegna), but I suspect it wouldn't make up very well as a coat, and in any case it would wear too hot.

Also, what about the details? I'm thinking of doing a two-button coat with two or three patch pockets. Should I ask for American-style machined edges? I suspect my tailor would be horrified, but still. Do machined edges look wrong with hand-sewn buttonholes? I'm not giving those up, so this would turn into a modus tollens argument against machined edges. For informal trousers lately I've taken a liking to flat-front with horizontal pockets (can't remember what they're called in English -- we call them 'alla carrettiera'). Again, any advice, pictorial or verbal, would be welcome.

Cheers.

Hmm, seems a charmingly interesting process, but not so sure how to go about it. And no, I'm not in NYC. I'm in the UK, and often in Italy.

Yes, that's the name.

Cotton Solaro! Good thought. Perhaps the kind with the plain twill rather than the herringbone: looks a lot less weird even with the red backing. Though a tone-on-tone version would be better. I'm sure my tailor has the ones from Drapers. Will check and report. Fresco or mohair are too formal for what I want.

But don't you agree that the plain twill Solaro is considerably less noticeable than the herringbone one? Despite the poor resolution one can tell the difference quite easily here (I think these are all wool though):
