Button Down Collar and versatility

Hey folks!

Possibly a stupid q, but is there any variance in versatility when it comes to how one wears a shirt with a button down collar?

Alongside wearing it buttoned up, I’d quite like to wear this shirt open over a t, akin to a work shirt almost, but I’ve never been sure if that’s “fine” if there’s the BD element there? Any thoughts welcomed!
