Reposhing this item I purchased from @alisondrausch. Loved it, but ready to rotate for something new. Pit to pit: Approximately 22" (note: slouched oversized fit, no defined pit) Shoulder to hem: 46.5" No fabric content tag, but this is almost certainly poplin. Light with a cotton feel, wrinkle resistant. Super comfy and easy to style--prepare for compliments! Questions? Leave a comment below!
