I'm from the US and in my 50s, and read quite a bit, but never encountered the word 'bespoke' until a couple of years ago. Not sure whether it's rising in popularity or what. I see it fairly often now.

Basically, "bespoke" has been used in the US in reference to goods desired by or consumed by the English gentry class.
Recently I've begun seeing it used to describe anything where you'd paying more for ostensibly hand-selected products. The example that comes to mind is "Bespoke Post" (https://www.bespokepost.com/) - which is, ironically, pretty much the opposite of the historical meaning of the word.
It seems like the long-term impact of the "Hipster" culture on the SV world.
