Hi, y'all. I'm sort of at a loss with this one. Is it a robe with a specific purpose/use/cultural history? (It reminds me of a choir robe) Or just a gorgeous jacket? And, when/where is it from? Not sure why, but something about it makes me feel like I should post it here to try to get some more info. Things to note: --has pockets --open front --very stiff outer fabric --see photos for topstitched and interior construction details! Any information/ideas are much appreciated! Thanks so much!
