I think I mentioned this upthread or elsewhere, the Dickies work shirts sure do cover up a lotta gun and are cheap. They fit loose enough they will fit over whatever you are wearing anyway. They work great over the foundation garments preferred by domestic violence perpetrators, as seen on TV.
They make a variety of colors, including some two-tone that will make you they greyest gray man at the bowling alley.
And the other day I somehow tripped over a temporary special of the black ones linked above, that were only $10 in a pack of two. I figure if I have some extras they can stay in the truck for those days when I leave the house wearing something that is too warm once the day warms up, but I still need to cover up a gun.
