Anything and everything (or nothing), except never again a wig or makeup.
My SO objects to a bra or forms, so when she is here, I respect that. Except when it is too cold for us to afford to heat the house to a civilized termperature, it's usally a cotton knit pullover dress for me. When it is too (*$$!^ cold, then I wear sweats, sometimes with pantyhose and/or knee-highs underneath.
