Fashion industry observers say it's not just celebrity moms who mimic their daughters' styles — many ordinary mothers do, too. Researchers tried to quantify the trend in a study led by Ayalla Ruvio, a marketing professor at Temple's Fox School of Business. Based on a survey of 343 Israeli mother and daughter pairs (ages 44 and 16, on average), she found that, in cases where mothers and daughters viewed each other as fashion-savvy and respectively youthful or mature, mothers were significantly more inclined to imitate their daughters than the other way around.
