If you’ve ever dressed up as a movie or television character for Halloween, the costume you bought was probably made by Rubie’s. The odds drop a little with generic characters like witches or vampires—plenty of smaller companies make those—but with more than 20,000 costumes and accessories for sale at retailers like Walmart, Amazon, and Party City, Rubie’s has probably played a part in your Halloween festivities. What started in 1951 as a soda shop/novelty store in Queens has, over the past 65 years, grown into an international business that earns hundreds of millions. (It doesn’t disclose figures, but the analytics firm IbisWorld estimates $251 million in revenue in the U.S.) Rubie’s has 3,000 employees, contracts with 12 factories in China, owns four factories in the U.S., and runs six large warehouses, four on Long Island, one in Arizona, and one in South Carolina. Rubie’s has also spawned 15 subsidiaries in countries such as Japan, the Netherlands, and the U.K. It sells Carnival costumes in Brazil, Day of the Dead dresses in Mexico, and Easter Bunny and Santa Claus suits around the world. But in America its bread and butter is still Halloween. ... Americans will shell out a record-breaking $8.4 billion on Halloween candy, costumes, and decorations this year, according to the National Retail Federation. That figure has jumped almost 70 percent in just 10 years, making Halloween the second-largest holiday in terms of decoration sales, behind Christmas. ... Rubie’s tries to anticipate Halloween trends a year in advance, but it’s constantly adjusting its plans as expected blockbusters flop (The Legend of Tarzan), beloved actors die (Gene Wilder’s Willy Wonka costume will be popular this year), or millions of people get swept up in the Pokémon Go craze and Beige finds himself mass-manufacturing last-minute Pikachu costumes to fill thousands of back orders. ... unlike regular clothes, which are subject to high import duties, most costumes are considered “festive apparel” and can be imported duty-free.
