Re: Another observation

Yes, why don't you go to some place like Whole Foods and take her with you. Let her find some lotions, deodorant, soap, etc. that she thinks smells good and will actually use. Then you smell them and see how you react. There should be some there that you feel fine with, you could get those.
Or if she doesn't want to go, then ask her what some of her favorite scents are (or if you already know), then go get one or two nice lotions you think she'll like and give them to her, ask if she likes them (if not, return them) and see if she'll try using them INSTEAD of the ones she is currently using.
