I have one of the 5.11 Undergear Conceal Carry shirts. It works well with my Sunday button up shirt and slacks. It is not the fastest but the gun is secured in a pocket under the arm, magazines under the other arm.

(I'd post an image but I never can remember how to do it.)
While I'd still suggest that you find a traditional type of holster, this may be a alternative way to carry.
Now if I can just solve the same problem you're having with my wife.......
