IIRC, the Gunfighter/Johnny Cash and white ice cream man uniforms came in when Zumwalt was CNO and making egalitarian reforms post-Vietnam. He let the senior enlisted wear beards, and got rid of the cracker jack uniform, replacing it with the the same basic pattern uniform for everyone from enlisted through officer.
Later, the cracker jack was returned (why? traditionalism under Reagan, or because moms and horny girls though it looked cute), but they kept the service dress uniforms. So sailors had blue and white dress uniforms, a white and blue (black) office uniform, a daily working uniform (khaki for chiefs and zeroes; blue denim for enlisted; and poopy suits for you bubbleheads). That was five different uniforms, not counting the peacoat, short black jacket, long raincoat, and the colored sweaters if you were in aviation. (and also stuffed in your duffle bag were civillian clothes to wear on liberty so you wouldn’t be beaten up by townies.) More uniforms than a Austro-Hungarian field marshal.
