Much of my LE career was spent in uniform, so that eliminated a lot of wardrobe decisions. But I was a fanatic about looking sharp and proper in that uniform. I could iron creases that would put razor blades to shame. As one advances in rank, one has to set the standard, and I did. I expected the same from my troops. LE is supposed to look professional. My department paid a uniform allowance to make sure we looked professional.
When I did move into detectives my bride, who is far above my league in the looks department, took over. She always dressed very professionally for work. When we would go to formal balls, when she entered she rocked the room. All this without being gaudy. She has the ability to groom herself and dress with class. As the detective division commander, I became her project. It worked well.
We are retired now, living in a remote western mountain community that is valued for its outdoor lifestyle. The preferred trousers here are Wranglers. New ones for 'formal' (as much as it gets here) events, the older ones for town and every day use. Now, as then, I maintain a short haircut, am well groomed, clean shaven, and dress well but comfortably when going out. My bride still shops for me. Good clothes, even (gasp!) casual, are expensive.
We very frequently encounter people whose grooming and dress are far less than what we would allow for ourselves. For us though, the old habits live on.
