The early 1900's - Edwardian era saw a fashion style of a jabot (a fall of ruff or lace attached to the neck band at the center front) worn by many women of the period. It was a pretty embellishment to high neck collars or neck bands.
This jabot is made of batiste fabric with two rows of inset lace with the same lace edging the three sides. The top edge would pin to the neck band or collar. Soft pleating also gives the jabot an extra touch. Length of the jabot is 9-1/4" long. Pleated the jabot measures 2-1/2" wide. Very nice condition although a slight touch of oxidation from storage.
