Most employees fast food, construction, labor stuff wear uniforms. Steel workers and most company workers wear steel toe boots, no ripped jeans and a form fitting t shirt. Office workers are mostly casual wear.
Management and up, those who deal directly with the client usually wear suits, dressy stuff, almost formal LOL most of them look so uncomfortable.
I remember one time I had a meeting with a president of this company. I wore a pair of pants, a tunic top and a pair of flat shoes. (so comfy) I walked in and he was fully decked out. I made him take his jacket, vest and tie off. Told him the meeting wouldn't start till he did lol I commented that the meeting went way better after I seen how comfortable he was. I must say he was a little shocked at my request hahahhahaha
