Every little girl is familiar with Barbie and probably owned one during her childhood.  Well look out because Barbie has a few new friends in her clique!  Mattel and one of their talent designers, Stacey McBride-Irby, have created a new line of dolls called the So In Style Dolls or S.I.S.  Their names are Kara, Grace and Trichelle and they are a hot new threesome that live for fashion.
