Left to right of top picture is (1) Candi Couture (Hispanic headmold) MiKelman Candi - Hamilton Design Systeme distributed by Paul David, (2) Donna Karan Barbie (1995), (3) a random playline Janay by Integrity (I can't remember the name - Fashion something or other) from 2003? 2004? I believe designed by Jason Wu, (4) 5th Avenue Fortuny Candi by Integrity toys - Jason Wu facepaint but not sure who designed the dress and (5) Barbie Looks #8. These dolls are all wearing their original outfits in the picture.
There are many different versions of Candi with different headmolds. I think the orginal Janay dolls had a different headmold as well.
