'ordered?' is the definition.
Both the definition and answer are adjectives. Perhaps they are linked in a way I don't understand?

(Other definitions for bespoke that I've seen before include "Made to measure" , "Tailor-made" , "Custom-made" , "Description of tailor" , "Of clothes, made to order" .)
