Lady Denman's stomacher has two circular ribbed motifs. She wears a ruffle-like headdress of small pearls that point forward like an attifet. Her upper sleeves are decorated with jewels She appears to be wearing a cameo of Queen Elizabeth, similar to the order bows worn by later royalty and nobility. Another preview of things to come is her lace apron that covers her entire under-skirt. All in all, an unusual dress.
