Zara Basic Brown Banded Blouson Top w/Pocket Small

Preowned condition. Brown silky top with blouson waist by Zara Basic. Women’s size small. Wide elastic bands at cuffs and hem in black. Large pocket at waist. Fabric and care instruction tags have been removed but this *feels like* a silky polyester. I’ve machine washed in the delicate cycle and hung to dry. Approximate flat lay measurements are: 18” bust and 25.5” length. Could possibly fit a medium, as well.
