n.

1886, American English slang, varied reduplication of dazzle (q.v.).

My confrère, The Chevalier, last month gave a new name to the scarfs of disjointed pattern when he called them the razzle-dazzle. The name was evidently a hit of the most patent character, for in several avenue and Broadway stores the clerks have thrown out a display of broken figures before me and explained that the ruling style at present was the razzle-dazzle, and the word seems to have been equally effective with the public, for when it is quoted by the live salesman, the customer, I am told is at once interested and caught by it. [“Clothier and Furnisher” magazine, Jan. 1889]

Meaning “state of confusion” is from 1889.
