It seems that most CDS started out with mom's slips and then moved on to sis's dresses, and ended up years later wearing corsets, dresses, bras, stockings, high-heeled shoes, makeup, wigs - the whole enchilada.
I started out about 40 years ago wearing one of my first wife's nighties (it was her idea), and remain pretty much stuck there. Nightgowns, slips and panties are all I wear. So I have not slid down the slope, and it seems unlikely that I ever will.
I wish I could find some others who just want to talk about the sensuous feel of wearing a silky nylon nightgown.
