What is the author's style in The Easter Parade: A Novel by Richard Yates?

The language of the novel is simple English. The novel is filled with language that contains little slang despite the many eras it passes through. The writer does not introduce any of the avuncular that a reader might associate with the fifties and sixties, even though a large portion of the novel's plot is set in these decades. The novel also does not include the overly formal language that might have been present in the thirties and forties. Instead, the author chooses to write in a straightforward, grammatically correct language that underlines the education level of the main character.
