But one of the queer results of the evolution in fashion is that a lot of society girls from Park Avenue have reverted—and "gone Broadway," becoming models, torch singers and even chorus girls.

The Park Avenue bug usually bites hoi polloi in one of the four or five East Side bistros that cater to the high-tipper set—Stork Club, Colony, Armando's, or El Morocco.

An attaché—say a press agent, headwaiter or even the boss—is swept off his feet by patronage of aristocracy; when the debutantes call him by his first name, the ex-barkeep begins to think of marrying one.

Unless a name is in the Register, he gives it a table in left field. He becomes the complete snob, an insufferable boor, and ends up being a chump to the congenital bluebloods and those who knew him when.

Now, some East Side night spot impresarios are hot to hire D.A.R. names, for tone, réclame and "contacts."

Sherman Billingsley of the Stork once thought it good business to engage a group of society girls to publicize his place.

"Maybe the debs can't do the job as well as the regulars, but they don't go ga-ga when they see a DePuyster," he said. "Besides, even if they don't get printed publicity, their friends come to visit them, which brings in business, which is what I'm in business for."

Not all who "go Park Avenue" are fakes or phonies. For the wealth, the fame and the acclaim that go as rewards for talent, endeavor or outstanding beauty also are on the East Side.

Those who achieve—via business, the arts, or charm—soon find the orbit of life has swung away from Grand Street or 42nd Street, as it had from Sioux City, and now extends from El Morocco to the Stork.
