I love wearing a slip! Full slips, half slips, pants slips, camisoles, I love them all and adore having them as part of my wardrobe!
Now you have to understand that I grew up in an era when women would not ever wear a skirt or dress without a slip underneath it, so that is what I was first familiar with. But once I started crossdressing and experienced the absolute joys of lingerie, then YES, I absolutely understood when women loved the feeling of them. Plus, they tend to make the dress fall better and look smoother, so that is a benefit as well.
