So my partner knows I like to crossdress I told her a few months ago. She was shocked but kinda laughed about it. But she has said she doesn't want to see me dressed up. I only wear womens sleepwear around the house. When I told her I like to crossdress I said I'd like to one day wear nighties to bed, we had a discussion about it, but I still only do it when she isn't home.

So I haven't been sleeping well lately and that's because I've been wanting to wear a nightie to bed as I honestly do sleep better when dressed, I have a draw of womens sleepwear in our bedroom that she knows about. but I don't know how to bring it up to her that I want to wear a nightie to bed
Any suggestions
