Love this dress, it just gaps at my chest too much (I'm a 34E for reference). There is no size tag, but it measures 21 inches pit to pit and is 45 inches long. There is some slight discoloration on the armpits but it's barely noticeable (I actually didn't even notice it until photographing it just now and I have worn it several times). There's no material tag but feels like maybe a silk linen or cotton blend. It's very light and comfortable, the fabric is a bit textured, I think through wear or incorrect washing, but it suits the style of the dress.
