Bachelor Auction, and often there will be a "theme" such as "Casino Night" (less dancing and more gambling, with all the house profits going to the charity).
The dance or gala is organized by a wealthy executive or socialite, and it is typically held at a large, upscale venue, such as a luxury hotel or convention center. While the ostensible purpose is charity, and while that may motivate many participants, there are a number of other benefits, including tax write-offs, social networking, and being seen at an elite event. The tickets may cost thousands of dollars, which ensures that everyone present is wealthy. The event may include cocktails, a formal dinner, and speeches. The men wear tuxedos and women wear elegant gowns and jewelry.
A common twist in fiction is for criminals to attempt to steal the proceeds; this was almost the entire use for charity balls in Pulp Magazines and Golden Age Comic Books. In aid of this, the Charity Ball may also be a Masquerade Ball to make it easier for the crooks to infiltrate.
In romance plotlines, it's a chance for the heroine to see some important personality traits of her prospective love interests. The Charity Ball is the natural habitat for the wealthy socialite and the Millionaire Playboy.

- In the South Park episode "Safe Space", a group of celebrities organize a charity ball to promote awareness for online shaming. The living embodiment of Reality crashes the ball and calls out the very concept, saying that only $300 was raised while the celebrities spent half a million to treat themselves.
