Theory black buttery silk dress with split sleeves

Long sleeve, split down the side, button down back with black mother of pearl buttons. To-die-for fit and feel. So airy and luxuriously buttery. Another item I'm in love with but it's a bit small for me so will look better on a slimmer build. Near perfect condition. See photos for condition details. Invisible when wearing it but the mild sweat residue in the armpit can likely be completely removed via cleaning. The front photo shows creases in the front of the dress, this is just a fold that can be steamed/ironed out and not a defect. Fabric is not stretchy at all.
