I believe it is time we went back to a work dress for office workers.
If we had a real #3 service dress that was both practical and decent looking we could keep our wool #1s for fancy occasions. It would have to be far cheaper to have Denver Hayes/Dickies/Eddie Bauer make us a green/tan, blue, and black work dress, than it is to kit office worker out in CADPAT/NCD. They could likely leverage existing designs with minor modifications to create better looking, and more durable uniforms than what we have.
Also, it would make going ashore in a foreign port easier, as the uniform bits wouldn't look so weird lol.
