Black mini dress w/ open back

Super comfy and flattering black dress. 3-quarter length sleeves, so it sits right below the elbows. The front is plain black and cinches in the waist to compliment figure while the lower skirt flares out a little. The back is open with floral lace surrounding the shoulder blades and is pinned back with a button at the top of the neck. Only worn once for sophomore year homecoming. At 5’10 this dress sits at mid-thigh if not a little above Can be washed in machine on delicates, preferably by itself or in laundry bag
