The Ballet Costume
I was about 7 I think. My two older sisters, my older brother and I were playing in the basement. We started doing "shows" for each other. At one point my brother and I found our sisters old ballet costumes in an old trunk. We put them on and did a a "show". Just silly childhood play, lasted a couple minutes and then we moved on to something else. But it made an impression on me. As I grew up I always had a "thing" for girls clothing.
My fascination with feminine clothing was reinforced when I was about 13. My older sister was getting ready for work and she was in the bathroom doing makeup. She was wearing a red leotard and I stood there talking to her and lusting...Not for my sister but for the leotard she was wearing. After that I was hooked.
