In the English language of yore, the verb bespeak had various meanings, including "to speak," "to accuse," and "to complain." In the 16th century, bespeak acquired another meaning—"to order or arrange in advance." It is from that sense that we get the adjective bespoke, referring to clothes and other things that are ordered before they are made. You are most likely to encounter this adjective in British contexts, such as the 2008 Reuters news story about a young pig in Northern England who was fitted with "bespoke miniature footwear" (custom-made Wellington boots) to help it overcome a phobia of mud.
