I think the underwear belongs to Ambivalent Girl Momoko. The top is from a set I got from Amazon last year for Best Friends 4 Ever dolls (I don't have the doll, but found the clothes to be cute and the price affordable).
Before I start sewing for Ruruko, I wanted to see what clothes and shoes I had on hand that would fit her. In the photo above, she's wearing shoes from Stacie and friends from the Pizza Party line.
These are some ballet shoes that I've had for a while. The blue ones and the pink ones on the outer left are too small. The cream pair on the right is too big and the pink pair, one away from the left fit perfectly because they are soft. The ribbon is too big and too long, though.
I can't remember whose shoes these are, but they are soft and fit snugly.
**Edit: Ms. Leo has advised that these light coloured purple shoes belong to my Happy Family grandmother! Thanks, Ms. Leo.
These are Kelly's slippers.
I think these are Stacie's also.
I found Polly Pocket Stacie and Janet outfits. Here she's wearing Janet's all-in-one shorts outfit and Teen Skipper's jelly sandals (They are a little long in the toe area) and taking Barbie's dog for a walk.
This is an outfit for a Kid Kore doll (Stacie size). There's an overskirt, fanny pack and cap to go with it.
