NWT Alice + Olivia dress

NWT Alice and Olivia dress, size small - missing beads on bottom and some marks/discoloration from storage (see photos). There’s a spot on right arm that’s hard to see when worn and one small pen line on back of dress. These may come out with spot cleaning or dry cleaning - I’m just not sure and don’t want to ruin the fabric. Retails for $484 but selling for a steal due to condition.
