“I love communicating and sharing information. It is just a way to connect with other people,” said one party attendee.

At the head of this class is Social Media Expert Jewel Figueras who selected each of these powerful women.

“It has been said that most consumers would like a stamp of approval from a friend and someone they trust,” said Figueras to CBS4’s Jorge Estevez.

“We are sharing it with millions of people not just thousands. We are tweeting and we all have a large follow base,” said one woman.

All that influence is nothing to brush off during times where every sale counts.

“We really are able to reach so many different outlets it is efficient and instantaneous,” said Eileen Alkabes, who works in the marketing department at Bloomingdale’s.
