KB Toys sold these great little princesses under the name name Once Upon a Dream. They ranged from $3 on sale to $5 full price. There were 5 princesses, Cinderella, Princess Beauty, Rapunzel, Mermaid Princess, and Snow White.
The clothes are nice enough fabric, not sewn too well, but they do redress well with Kelly Dolls.
There was also a line called "Before Once Upon A Time" sold at Toys R Us and Disney stores. There were 4 packs of princess, ballerina princesses, as well as 3 sets (that I know of) with accessories and playsets.
These dolls had slightly higher quality. They also redress well with Kelly dolls and pair up well with Barbie doll gowns.
