Where does “zoot” come from?

I can't write this etymology because the chain provided doesn't support the headword "zoot." The chain traces "suit" (from Old French sieute through Proto-Indo-European sekʷ-, meaning "to follow"), but you've asked me to write the etymology for "zoot," which is a different word entirely (historically slang for a zoot suit, ultimately of uncertain origin—possibly from Yiddish, jazz slang, or reduplication of "suit"). Could you clarify: did you mean to ask for the etymology of "suit," or do you have a different etymological chain for "zoot"?
