For a dressy look than tacticool:

Ken is a great guy. I have one of his nice ones for semicasual dress up.
I've also worn Concealed Carriers and nongun folks don't pick it up as tac.
For matches, I have some cheapy nonbrand with a rip in it I got on the discount rack at Academy. So I don't care if it gets knocked about.
I do agree with Tam and floppy shirt look and nice t-shirt underneath. Quite common here.
