Great stuff all y'all!
The Old Navy in-port working uniform: Blue chambray shirt, Denim Bell Bottoms, dixie cup White Hat and a cup of mess deck coffee, extra strong. Beards were authorized briefly from 1970 to 1974 while Elmo Zumwalt what Chief of Naval Operations. The guy in the picture looks nearly identical to an old Engineman First Class I served with aboard U.S.S. Vega (AF-59), 1960-1963.
Nowadays its all different. Sailors are dressed more like Marines today with the new working uniform.
