Karen Millen lbd black sheath evening dress long sleeve lace Small

EUC Karen Millen black sheath dress with long lace sleeves, low back, zip back, sheer lace chest and shoulders with asymmetrical geometric hems on bust and shoulder. Dry clean only. A tiny unnoticeable wear spot on rear, couldn’t even capture in a picture. This dress is labeled a size 6, however imo it runs very small. I’m a size 2 with a small bust and it fits me well with a bit of space. Could fit a 4 but i doubt it would fit a 6 unless you like it skin tight and don’t need to sit down. See pic for material. 16” ptp, 13” waist, 38.5” length, slight stretch.
