Unfortunately, the tag is worn and size cannot be found. I showed measurements of width and length to help. My guess is this is at least a large but please see measurements. Length is 51.5 inches. I measure width in two places. Under the arms is just over 20 inches and in the mid section it is just shy of 23 inches.

Also, my guess is this is vintage but I cannot say for certain and therefore did not list as such.

It's soft and lightweight and in great condition.

Please message if you need further measurements.
