must be cold
Back in the seventies, going bra-less, to coin a phrase, took off. I had an employee who wanted to do it but was too shy, so she wore a blouse that had two bumps on it that made it look like you weren’t wearing a bra, but you were.
Her name was Virginia (”Virgin for short, but not for long”), and even the notion that people thought they were seeing her nipples, although they weren’t, was too much for her, and she stopped wearing the blouse. LOL
Every time she spread her legs, a little light came on.
