From sports uniforms to gang colors, groups have long established allegiances by their clothing. In “Women’s Writers’ Wear in Abolitionist America,” art historian Francine Farr lectures on the significance of women’s dress as it related to abolition, literacy, and image-making during the 18th and 19th centuries. Using photographs, she will contrast the dress of black, white, and mixed-race authors and describe how it reflected their support of the abolitionist cause. The lecture includes a tour of the DAR Museum’s period rooms and is held in conjunction with the “Talking Radicalism in a Greenhouse: Women Writers and Women’s Rights” exhibit. At 2 p.m. at the DAR Museum, 1776 D St. NW. FREE. For reservations call (202) 879-3241. CP
