I have a black sparkly sheer cocktail like dress that goes see through in the right light, especially if a camera flash hits it in the dark, but I'd never contemplate going out in without underwear. I always at least wear at least black
knickers with it, maybe not a bra. Maybe when I get back home I'd dispose of them...........
I'd rather be known for what I had on underneath, than be known for not having anything at all! I am a naturist, but still, I'd never go out with really close friends and display my goods! Others may want to, but personally its not for me. Its just too short as well to be comfortable without
knickers.
