None of what you said is wrong but I lean more toward "treat people like adults until they give you a reason not to."
Periodic inspections are onerous and a waste of time unless you're specifically having dress and appearance issues in the unit. If dudes are coming in with dirty, torn up flight suits, unshaven, and with hair out of regs, then maybe it's time for a blues day. But only for those specific individuals and only for as long as it takes to fix the problem.
The uniform is a tool to teach attention to detail, unit cohesion, and pride in your appearance. Much like other silly things you get reamed for in boot camp, its importance wanes massively once you get real responsibilities. Years of training later into the fast jet business, dress and appearance should be a given. Not something you need to periodically spot check.
If you trust people to fly multi million dollar supersonic aircraft, you should trust that their uniforms are in order.. unless they specifically give you a reason to think otherwise.
