Saturday, I attended a poetry reading that was organized for 100 Thousand Poets for Change Day. It was a lovely day, so the event was held outdoors, which was really appreciated.
It is rare to go to a poetry/literary event that doesn't have at least one attendee in the de rigueur poet's outfit. For late fall and winter events, a black turtleneck is worn in place of the tee-shirt. For spring or fall, socks are generally any bright color or pattern. No socks are worn in summer, and in winter, black boots are the footwear of choice.
