Linda (first wife) only wore a bra in uniform or with fancy duds. I memorably picked her up after work with a change of clothes; she switched from Navy blues (with skirt and pantyhose) to jeans and a sweatshirt, in my front seat, on the Beltway, at no time showing any appreciable amount of skin. And when I thought she was done, she popped out her arms from the sweatshirt, one hand holding her bra.
At some point that incident (or something similar) is going to make it into a story of mine...
