This morning I had on a polyester dress and went out side to check something in our car. Opening the door and sliding in I could feel the dress slide against my panties. When I got out a gust of wind blew against my dress. Coming back into the house I straitened the skirt and felt the dress slide once again over my panties. I didn't have on a slip, but the fabrics easily slipped over each other. I love wearing dresses that are light and airy. When I was in high school I went on a carnival ride with a girl that slid in my lap thanks to key layers of nylon. I ran my hand over my hip just to feel the dress slide over my panties one more time. That made me happy! I have some blouses that slide over my bras as I move.
