This vintage scarf is truly unique. The perimeter is approximately 16.5" on each side; however, the scarf has been split to fit around your neck. Very pretty, unique color combination. Some small flaws as expected with a scarf of this age. Feels like silk, but no tag to confirm. Unnoticeable when worn; please see final photos for close-up images. Brand: unknown Shape: square Dimensions: 16.5" x 16.5" Color: apple green, spring green, pale tan, creamy white, red Pattern: floral Fabric: very lightweight
