I bought this from Poshmark last year and have never worn it, I did wash it. I am not sure what size it is, no label. It measures 18" laid flat from arm pit to arm pit and is 34" in length from shoulder to hem. If I had to guess the size it would be a Medium to a Large, but because it is open in the front, someone a little bigger it would fit. I wear a XL to 1X and it is snug and tight in the arms for me. Such pretty lace. It is in good condition, a couple flaws, but not noticeable. I was bummed when I got this that I was not able to wear it. My items come from a smoke free home. If you have any questions, please message me. Thank you for stopping by my closet. Happy Hunting!
