I have two bespoke garments: a suit I had made in Chicago in my last year of graduate school. It was beautiful and fit like a glove, but I gained a little weight and it was useless.

The other, you yourself pointed me to on eBay (my undying thanks), the regulation doublet made for a piper in Scotland. I consider it bespoke even though it was a standard form, because the cloth was unusual. He must have worn through too many doublets because this one was made to last. Even so, a lifetime of piping wore out the horiontal threads of the inner lapel; the vertical threads appear to be unbreakable!

My conclusion: you may not be able to draw any general conclusions about bespoke, because bespoke varies so much! But I can guess you are still hankering after a montrose?
