Domly? Nicely put.
Umm, My Dom usually will dress in a button down shirt, jeans, and shoes (not sneakers). Underneath He sometimes has a black undershirt. I love to picture Him leaving his shirt unbuttoned and untucked- better movement. Kind of a relaxed professional, point of authority look. Then if He gets real worked up, He could just remove it. The appearance of the black undershirt vs. white appeals more to me.
Honestly, though - so long as He's comfortable I'm happy.
