Boucle was introduced in the late 1880's and I would date this cape to right about that time. The body of the cape is boucle yarn dyed a soft olive green. The inside of the cape is lined in a brown fabric similar to glazed cotton, but not as shiny. I believe that the ties at the neck were added later and most likely, there was a soutache and button closure at the neck. There are formed shoulders in the cape as well. I believe this cape would have been worn by a young girl as it appears too large for a child and too small for a grown woman. The doll modeling the cape stands about 28" tall and the scale works well for a doll that size or larger.
There are a few minor pulled threads and there is a spot on the back, about the size of a quarter, where the yarn is completely gone and the brown fabric shows through. There is also a stain on the inside lining, and a few loose stitches. Otherwise, it's in very usable condition for a piece this old.
Measurements are as follows: 12" shoulder to shoulder, 11.5" long, and about 23" wide at the bottom. Please let me know if you need additional measurements
