Spent everyday in these for over a year on a high end celebrity detail, and didn't do the Bat Cap once. The nice thing is they are cut to be worn un-tucked and not look terrible. I carried a HK45C, two spare 10 rounders, a Strider DB all concealed in Raven kydex all OWB without ever having an issue in a very sensitive environment. The stuff also wears like iron.
While you wait for your permit, carry around your home (not just a few minutes here and there, carry as much as possible) and see what works and what doesn't.
You will probably find you'll need to make little modification to your current wardrobe, besides perhaps pants size if you'll be carrying IWB.
I have and wore the Polo's on occasion, but the ones below are what I lived in along with the Firehouse Work Pants:

I topped these with a Firehouse Shirt Jac or a Firehose Chore Coat if the weather was cold (the Malibu version of cold, not the kind with snow).
