EL PASO – This border city’s downtown shopping district has become a flourishing quinceñera Mecca as girls turning 15 and their families flock to buy lavish party dresses and accessories to celebrate their transition into womanhood. Outfitting quinceañeras, one of the most important celebrations among Hispanics, has become a booming business here where 82 percent of the population is Hispanic. “Customers are very faithful to this location. There’s a lot of traffic coming from everywhere. There are even people coming from outside of Texas,” said Yuridia Villagran, co-owner of Imperial Real Boutique.
