Researchers at Temple say mothers tend to take fashion cues from their teenage daughters and not vice versa. "Literature showed that kids tend to mimic their parents' consumer behavior, as a simple form of learning," says Ayalla Ruvio, the Fox School of Business marketing professor who led research that showed the opposite to be true. "It's a phenomenon in which mothers are mimicking their daughters." Ruvio attributes the change in behavior to a savvy group of teenage consumers and a growing number of moms who want to retain a younger image.
