This antique Cravenette rain coat from Stoughton Rubber Co. has a design feature that I'm unfamiliar with, and I'm hoping someone can provide the name and purpose for this. The skirt back is pleated with buttons across the top and, at about mid hip, there are two pocket-like openings (one on each side). Would this have something to do with a bustle or what are your thoughts? Also, I believe this coat dates to the early 1900s, but please correct this if you know differently.
Thank you for your help!
