You have nothing to worry about if she is fine with you wearing. Furthermore, people tend not to notice that you are wearing a diaper underneath your clothing in public. In fact, I have worn thicker diapers out in public (Abena M4, ConfiDry 24/7) on numerous occasions, and no one noticed anything. The initial fear of a stranger noticing your diaper in public is completely overblown. The general public isn't nearly as observant of diapers as we happen to be.
