Whenever I would finish taking a bath, I would put on baby powder (a lot). Oh how I loved that feeling that I would get - I was just like my mother, primping and getting ready, feeling so grown-up.
My older sister told me that if I used any more powder, I would turn really white, ghost/sheet/snow white. After putting a lot on and seeing that it wasn't disappearing, I believed her.
I still don't use baby powder, even though I now know that it won't turn your skin a ghostly white.
