Beachlunchlounge top or mini dress.

Wonderful fabric on this long sleeve top or mini dress? Would look great with leggings or skinny jeans too. Tag says XS but I think it’s more like a S. Please refer to the measurements. Bell sleeves with elastic at wrists. 2 tiers at bottom. Split neck with tassel ties. Pit to pit: 18” flat Length from shoulders: 32”
