Look at Kangaroo Carry. It's great for deep concealment, works with non-fitted dress shirts, and is unnoticeable. Plus you don't need to worry about a gun belt, restroom issues, etc. You can feel it, but it's not uncomfortable, at first. When I'm in a tie, I'd have to lose the buttons on my shirt to get to my weapon, but that's a small price to pay if I have to defend myself. If wearing a golf shirt, you can access your weapon through the neck of the shirt. I also have an IWB Alien Gear that I like. If wearing a shirt untucked I'll use it. For business attire it's Kangaroo Carry.

Only drawback to Kangaroo Carry I have found is it gets a bit warm in the summer time.
