Quotes are done in polo or other nice logo’d shirts.
Logo’d tshirts for when I’m working :). Polo or long t-shirts, if cooler.
Work pants - always same colour. If I had employees, every one would have to wear the same style/colour pants or shorts.
Shoes - I have mixed feelings about this one. I feel like it can be between select colours. Black, white, brown.
Or, maybe 1 colour only.
Hats and company jackets are also a solid choice I find shoes aren’t as noticeable if coats and hats are worn as well.
I have worked for both kinds in the trade industry. Full uniforms and then just logo’d shirts with what ever jeans or pants. Though, never getting a complaint - full uniform is the winner in my book
Make it comfortable, make it simple. Make it consistent.
