Retro 70's Corduroy & Faux Fur Jacket

This jacket is so darn cute! Too small for me now (fits like a size 2/4). Removable faux fur collar (see pics). The tag says it's a Medium, but it must be junior sizes. I'm typically a size 4 or XS/S. Note: the button in front of the diaphragm area doesn't seem to want to stay closed, but with the others around it closed, it doesn't cause a big issue.
