Marcia Seligson calls the wedding dress the "key metaphor" in the elaborate effort to make the American wedding an "idealized departure from reality", and notes that in the early 1970s, at a time when love-ins, live-ins, and hippie weddings were throwing brickbats at tradition, 94 percent of American brides still chose to be married in white. The color has long been associated with weddings because of its supposed symbolic link to virginity. Commenting slyly on the tradition, Judith Martin (1982) observes that an engaged couple needs to decide "whether wearing a white wedding dress will be worth enduring the sneers of people who believe these must be accessorized by intact hymns".
Viewed historically, the link between white and virginity (or, as it is sometimes euphemized, purity) is not as absolute as is often supposed. Brides
