When did the cracker jack name become the uniform of the navy?

Answer 1

The term "crackerjack" became associated with the U.S. Navy in the late 19th century, specifically around 1886, when it was used to describe a type of sailor who was exceptionally skilled or competent. The name was later adopted for the navy's uniform, particularly the blue and white dress uniform, which became a standard by the early 20th century. This term has since become a colloquial reference to Navy sailors.
