Desert Boots and khakis are good. Shirt is fine. Thumbs down on the denim trucker jacket. Denim is for yard work and in this case, driving a big rig. A suede blouson would have been a far better choice.
You should leave that jacket in 1986 where you found it… acid wash denim was a big no-no then and it still is a big no-no now. The shirt does not work on its own with the pants either.
I absolutely love the boots and pants, a white cotton shirt and a fitted dark blue denim jacket would bring this outfit to the next level.
By the way, you remind me of Morris Thorpe from the T.V. show “The White Shadow”. (Google that, you’re way too young to know what I’m talking about, LOL).
