Sexy black corset style mini dress (size small?)

Bought back when I was an exotic dancer and never wore! This dress is unbranded and does not have a size tag. Based on its fit on the mannequin I'd say size small (4-6). Black outside, beige inside. Halter neck with adjustable corset lacing on the back. Perfect condition, no stains, holes, or tears! Smoke free, pet free home
