Not very often will this come up for sale. AG doll Caroline Abbott's very pretty white nightgown, embroidered across the chest with blue flowers and green leaves. Scalloped like edge around neckline in front and follows through to the back. Two rows of white crochet accent down the front of nightgown with blue ribbon in both rows and a blue bow at the end of one row. The bow is correct on the one row only. Her nightgown is accompanied by the blue shoe like slippers that have blue bows on them. Hard to find piece. I've seen on eBay for $57 best minimum.
