I prefer a silk nightdress when I lie between my silk bed sheets.
Summer or winter does not matter. It is always stockings. If it is cold I wear a pair of longlegged wool underpants while outside, which I remove as soon as I get in. Stockings attached to a garter belt or OBG feels sooo feminine and sexy to me. I prefer RHT nylons for every day wear and seamed (FF) nylons for the more sensual encounters. Of course the lingerie have to match the outer clothes and be beautiful and sexy too.
A silk slip or babydoll. It feels sooo good moving around on my silk sheets.
