In American usage, a cotillion is a formal ball and social gathering, often the venue for presenting débutantes during the débutante season – usually May through December. Cotillions are also used as classes to teach social etiquette, respect and common morals for the younger ages with the possibility of leading up to a débutante ball. For different places, there are different cotillions. These days, most cotillions are for middle schoolers as a chance to teach manners and etiquette, and also are great times to socialize with friends at the after parties. The after parties at cotillion are usually fun (needs citation), with some food, drinks, and music.
