Vintage dress/housecoat with pockets

Very Madmen! Could be dressed up or down. Small stain near the pocket (see picture). Pockets on both sides. Lovely embroidery. The initials in the collar were there when I got it, I like the hint of a story behind it. No size tag, fits like a M. Chest: 22” Front length: 39” Sleeve: 20.5”
