The boots fit just about all 16" fashion dolls. They are tight on Ellowyne without stockings (especially the left foot).
Shoe Fit Guide
Good fit on all 16" fashion dolls - big in the foot on some, but it doesn't show. You could also pad the toe a little if you think the foot sits too far forward. A little large in the foot for Tyler and other 16" dolls, but it doesn't show inside the foot.
