I think I was about 8. And, since I didn't have any sisters, it was my mothers clothes. She was a part-time model for a local department store, so she had some real classy things. What I really fell in love with was her rubber Playtex girdles, in particular the open bottomed ones. I love(d) the feeling of stockings pulling on garter tabs :p It went from there to her other things, bras, slips, skirts, blouses, wigs, makeup, bathing suits. Did she ever catch me, no. But, I think she knew. Mother seems to always know :) Now, I have my own clothes, and a wife that really enjoys my dressing.
