Thanks, gents. I think the Smith Riband turned out really nicely. I was a little apprehensive about the small scale of the herringbone, but it's a beautiful fabric, and the visual texture is great.
I PM'd sacafotos, but I agree that he's probably looking for this from Drapers Seta e Lino (with credit to Greg/NMWA for the photos):Warning: Spoiler! (Click to show)
That stuff looks great, but iirc, it seemed too densely woven for hot, humid weather.
