Here endeth the lesson! Get a good pancake holster before you torture your brain any further.

Beyond that, just think about loose-fitting cover garments, not closely tailored clothing, and materials with some substance (canvas, broadcloth, etc) rather than soft knitted clothing that clings.

And just like Iggy said above, most people pay very little attention to anything around them, just as long as you don't shove it into their faces.
