Looking for patterns for 15" baby doll Sewing Machines Parts and Sales in Los Angeles

I’ve recently started sewing clothes for my daughter’s baby doll. It’s a 15″ American Girl “Bitty Baby”. I bought a set of patterns from McCall’s and I’ve made the doll pants, a shirt and a dress. But I would love to find some patterns on pinterest or elsewhere for some basic sundresses. I’m finding plenty of patterns for 18″ dolls, but not a lot for 15″ dolls. Can anyone help? Thanks!
