While mom and I were digging through all of our old doll clothes, we found this:
She told me that one of her fraternal aunts probably made it. It's completely hand sewn- tons of tiny blue stitches. The shoulder straps cross in the back.
I wanted to hang it for display in my sewing room, but since I always have the blinds open, I decided not to so that it doesn't fade. I will probably make a pattern from this one so I can make some new ones.
