This image is an excellent example of lace collars.
She wears three, maybe four, collars that combine to form a very effective modesty piece. The blandness of black and white is broken by an orange waist band and bows. Her son's jacket has puffed slashed sleeves. I attempted to detail-enhance the image to see what sort of bodice she was wearing, saw no waistline while reducing detail of the lace, and abandoned trying to enhance details.
