We already knew Kate Middleton's second-time-around maternity style was very, very chic, but the global effects of her pregnancy appearances are even more astounding.
The "Kate effect" was a game-changer for maternity brand Seraphine: The brand's profits have reportedly quadrupled since Kate began wearing pieces from the line, and their global presence has also grown astronomically, too.
E! News caught up with Seraphine Founder and Managing Director Cecile Reinaud to get the scoop on how Kate's pregnancy style has changed the way women shop for maternity clothing and why she thinks the Kate effect is still in full force. (It's worth nothing that Jessica Alba, Kate Winslet, Angelina Jolie and Gwen Stefani all stepped out in Seraphine during their pregnancies, but Kate, as Reinaud said, is the one who made the line a household name in America.)
