I am enamored with this beautiful hat. I do not believe it is antique; I am really not sure when it was made. But it has the perfect look for your bisque fashion. I have shown it on a 13 inch doll and a 15 inch doll so you can have some idea of size and appearance. I believe the fabric covering the straw base is silk or something that greatly mimics it. This bonnet has a great shape to it which is enhanced by the flowers across the top of it. Measuring around the face on the inside is a distance of 6 1/2 inches roughly speaking. This is a bonnet that will provide the finishing touch to a lovely outfit. Please feel free to ask questions or request photos. Do take a look at my other doll items and thank you for shopping Red Dog Dolls.
