One of my old boss's used to wear a white top & white bra's underneath. You could always see an outline but with a certain top & lacy bra it was really see through. She knew what she was doing, would give loads of downblouse glimpse's
My wife on the other had, even though she's an escort, she is mortified if she's got to much flesh or undies on show. But if anyone in the UK remembers(knows about) 'Thunder Thursday' a couple of years back, she got caught in it and when she got home, her clothes were clinging to her and her undies on full show lol
