The dress appears to be a one-shoulder, black crochet maxi dress with several distinctive features. It has a high slit on one side, a cutout detail on the waist, and lace-up detailing along the side of the slit. The shoulder strap incorporates metal ring hardware. The dress also seems to have some sparkling or sequined elements woven into the crochet fabric.
Based on the visual characteristics, it's difficult to provide a specific name for the dress as it would likely be part of a particular brand's collection. However, you could search online using keywords like "black crochet one-shoulder maxi dress," "high slit cutout dress," or "lace-up crochet dress" to find similar styles and potentially the exact dress if it's currently being sold.
