Job site attire

Hey guys, I’m just curious as to what you all buy and wear while working.

I’m planning on blue jeans but didn’t know is there was a better alternative or something heavy duty I should look into.

I plan on wearing long Johns while it’s cold and having a carhart jacket and bibs for super cold jobs, but I’ve never worked construction and need some guidance. I bought 8” steel toe boots so I’m good there
