Isn't that basically Avon/Amway with sparklies Jamis?
Anyway, on this whole "I don't want men looking at my wife thing...." Let me see if I can break it down here.
Not wanting your wife to be uncomfortable is fine. But if she has a semi-normal life that isn't really an option. Does she go shopping, out to dinner, out with friends etc? Then she should really already be familiar with men looking at her. Whether this is right or wrong is immaterial.
I don't know your situation. Maybe she was raised in a very isolated community that strictly segregates the genders, and attended an all girls school. Maybe she was raped and is terrified to leave the house. But even if she has been terribly sheltered or abused and is thus nervous about normal social interactions, fostering that is not healthy. Gently encouraging her to be more self reliant and confidant is your job as a husband, not trying to keep her isolated.
