Hush hush, Sweet Charlotte. Your ds may be trying to have you certified so he can inherit the plantation.
When you said "dress uniform" I assume you meant a military uniform and not something for a transvestite.
The military experimented with cotton khaki in the 1940s, but a starched cotton shirt was never a military dress shirt. They kept them around a few years for nostalgia, just as civilians kept their faded jeans.
