Another one of those strangely captivating words: "bespoke". It means custom-made, and especially applies to clothing that is specially tailored to an individual's order, not made from a pattern or modified from something pre-built. Besides clothing, bespoke can be used to describe any custom-made object or system. As  notes, it "... looks rather strange, because it's an adjective formed from the past tense of the verb bespeak ..." which itself is rather obscure. All I know is, I like it!
