Isabel Marant Etoile Barden Dress Size 38/US 6

Very good worn condition, Isabel Marant Etoile Barden Dress, size 38/US 6. I am guessing on the size just based on measurements as I had cut out fabric tag (see photo). So please see measurements to determine best fit. Dress is 100% silk with viscose lining, knotted detail at waist, subtle open back with button closure and invisible back zip. There are no rips or stains, but there are thread lines throughout the dress (see photos for example). It’s not noticeable because of the busy print. Dress does not come with belt pictured in cover photo. Measurements are approximate: Armpit to armpit - 19” Waistline across - 14” Shoulder to front hem - 41”
