One of my H's favorite things for me to wear to bed are his big floppy flannel shirts. I don't get cold easily and don't normally like to sleep this way....BUT he likes them on me. I can imagine even something that simple might be a compromise between silk (could still not feel like much to some women) and eskimo gear. I know you would prefer her in nada, BUT...some folks just aren't comfortable sleeping like that. I guess my suggestion is....pick something of yours out of the closet that maybe she likes (and you like) and suggest she use it as a night shirt....wouldn't hurt to try it would it?
