My work attire: Any t-shirt with a pocket, carhartt cargo pants or jeans, boots, and my safety vest with my company name embroided on the back, which my worker wears also.
When he first started he liked to wear shorts, I didn't have a problem, but he learned pretty quick why I always wear pants, and never shorts when at work.
My set up:
-2007 Chevy 2500hd 8.1l 4x4
-7x16 open trailer
-2011 gravely zt 52hd
-21" craftsman push mower
-Stihl trimmers, blower, edgers, chainsaws.
