Carriage Trade

“Carriage trade” means business with wealthy customers (such as those who arrive in expensive carriages). The term “carriage trade” has been cited in print since at least this description in The Saturday Evening Post in July 1907:
 
“Retail distribution is to-day separating into two distinct groups—high-class trade and popular trade. One caters to the classes, and the other to the masses. One is known as ‘carriage trade,’ while the other has been wittily dubbed the ‘baby-carriage trade.’”

October 1910, McClure’s Magazine, “Workings-Girls’ Budgets” by Sue Ainslie Clark and Edith Wyatt, pg. 609, cols. 1-2:
The fortunes, talents, tastes, eager human effort spent in shop- window displays on Fifth Avenue, the shimmer and sparkle of beautiful silks and jewels, the prestige of “carriage trade,” the distinction of presence of some of the customers and their wealth and their freedom in buying—all the wordliness of the most moneyed city in the United States here perpetually passes before the eyes of Zettas in their 1.20 muslin waists so carefully scrubbed the night before, and of Alices who have had breakfasts for 10 cents.

August 04, 1993|JONATHAN KIRSCH | SPECIAL TO THE TIMES
When it comes to the folkways of the rich, the powerful, and the privileged, Stephen Birmingham knows what he’s talking about. He has chronicled what passes for the American aristocracy in a couple of dozen books (“Our Crowd,” “California Rich,” “Life at the Dakota”). And his latest novel, “Carriage Trade,” is set in the same glitzy neighborhood.
 
“Carriage Trade” is the story of Tarkington’s, a fictional Fifth Avenue department store whose founder, Silas Tarkington, is found dead under suspicious circumstances in the swimming pool of his country estate.
