The red print shirt is tagged Ideal. The green silky shirt I am told is for Madame Alexander Alexander-Kins dolls. It has the remnants of a tag on the back of the shirt.
The button up shirt is not tagged. I was also told the pants are for Betsy McCall but they are almost as tall as she is so not for her. They measure 6 inches from top to bottom. They are in played with condition but still nice.
