how can I concealed carry as discretely as possible?
practice at home. You should be comfortable sitting in various chairs/car, bending, kneeling, hugging family, reaching up high... everything you would do already as a habit, but without printing the firearm. Sometimes you have to be aware you could print or expose the firearm and adjust your habits accordingly as much as it is dressing around the gun.
