vintage red puff sleeve robe

incredible vintage piece. beautiful long sleeves that are puffy on the bottom half, with lace details in a line thru the center. not in perfect condition because it is in fact missing the center button to keep the thing closed so its safety pinned in the pic. will include the safety pin just in case but yeah there is no button there sorry. no tags or anything but i would call it a M-L and the length from top to bottom is 56 inches.
