Vintage 1970s “An Original by B and K” Dress, Large, Newly Restored

This vintage dress is gorgeous. I’ve tried to find out anything about the brand, but it’s from the 1970s and has gorgeous embroidery. I bought this at a vintage store in Chicago for $128 and unfortunately it no longer fits me, so I’m trying to make back just some of the money I spent. I still have the tags from the vintage store, has not been worn since it was restored. Offers welcome!
