A class act is a performance or personal trait or behavior that is distinctive and of high quality. As a noun phrase, it is typically used to refer to a single person, a team – such as a performing artists working together – or an organization.
In sports, a "class act" would be an athlete who not only performs exceptionally well, but also exhibits a range of other admirable qualities, on and off the field.
In dance during the jazz age and the swing era (the first half of the 20th century) – tap dance in particular – a class act was, and still is, a complimentary reference to a dance team that exhibits precision, elegant dress, detached coolness, flawless execution, and dignity. In 1946, after serving in the Army, Charles "Honi" Coles and Cholly Atkins collaborated as a dance duo that became highly acclaimed.

Atkins, in his 2001 book, Class Act (co-authored with Jacqui Malone), stated that,

Atkins' and his peers aspired to pure artistic expression driven by a desire for respectability and equality on the American concert stage.
Marshall Stearns, in the 1964 film-made-for-TV, Over the Top to Bebop, stated that the class act "started with the soft-shoe and the sand and the shuffle; and it grew up and became a dance in which you showed elegance and dignity and precision. And every class act in the thirties and forties had their own soft-shoe."
A "flash act," in tap dance, includes acrobatic movements. The Nicholas brothers, who famously performed class acts, also did flash acts.
