Sweetie Pops

I never knew what these dolls were called, but I had them growing up.  I was fascinated by your info page and surprised that I had nearly all of the fashions (and both Caucasian dolls).  I think the only fashion I didn't have was the second unknown fashion.  I was bored and searched on ebay.  There was a fourth doll:

Ballerina:

Her hair is up in a topknot instead of in pigtails.

So, the Unknown Outfit #2 is probably called Ballerina.

The third one is definitely pajamas.  I remember those and used to be upset because I only had 1 set but two dolls, so they couldn't have a slumber party.
