cotillon

Cotillon is French for a petticoat or underskirt, diminutive of cotte (coat, tunic). The dance was named after the garment because the steps — particularly the rapid turns and skirt-swishing movements — made the petticoats visible and dramatic. The cotillon was a French ballroom dance of the eighteenth century, danced by four couples in a square formation. It was a social dance: the figures changed, partners rotated, and the dance required both skill and cooperation.

The cotillion crossed the Atlantic with French culture. In American high society of the nineteenth century, the cotillion became the central event of debutante culture — the formal ball at which young women were 'presented' to society. The dance gave its name to the event. A cotillion was no longer just a dance; it was the ball itself, the social ritual, and the entire apparatus of upper-class debut.

The American cotillion reached its peak in the Gilded Age. Mrs. Astor's cotillions in New York defined the social calendar. The tradition established a template: young women in white gowns, escorted by young men in tuxedos, presented to a receiving line. The dance was still performed, but the social ritual had consumed the dance. The petticoat became a party.

Cotillions survive in the American South and in African American social organizations like Jack and Jill of America. These modern cotillions are often community events focused on etiquette, service, and social development rather than social exclusivity. The word has traveled from a French undergarment to a formal dance to a Southern social institution. The petticoat would not recognize its own name.
