In my early years of dressing, I loved slips, I had full and half slips.
I currently own on full black slip, and a shorter nude coloured one. I must be lazy, as I rarely wear a slip with a dress, + plus the slip I have is just a tad longer than the dresses I own and it is a faux pas to wear a slip longer than your dress.
I have skirts with no lining, so at times I would wear the half slip with those skirts. But again, I am getting lazy and I just wear non lined skirts as is.
