For me, it was a body shirt when I was about 8 years old. It was silky and had the crotch snaps. I think my Step Mother should have just given it too me at that point because I think I wore it more in secret than she did. I was lucky enough to get away with trying on a lot of her things as I grew up, always in fear of getting caught. I know she had to have known, but she never said a word. I remember falling asleep one day in my teens dressed to the hilt under the covers. Panties, bra, blouse, skirt, everything. I wasn't expecting anyone home till late that night. My Father opened my bedroom door and said "get your butt up, it's 3 in the afternoon," and then shut the door. OMG I was never so freaked out in my life, not before or since. Then I had to undress and try to put everything back without him hearing me upstairs (it was an old house). I was never so happy to hear a lawnmower start in my life!
Just thought I'd share.
