I may be starting a new job soon that will require a more professional dress code than I am used to, and am wondering if any of you who are carrying in a business casual scenario, had any tips on holsters, and carry locations. My current daily attire would be a Dickies work shirt with jeans or work pants, so I usually carry my CZ P07 in a Harry's Singleton at the 4 o'clock position, but I'm thinking that with a dress shirt tucked in, that might not work well.
