Opaque Black Tights - Brand New, Never Worn

Brand new, never worn opaque black tights. Opened the package and tried on but they didn't fit. I think they said for up to 140 lbs, but they must be for shorter ladies than I (I'm 5'6"). Probably a Junior size medium or large, or an adult size small. New condition, no tears, rips or holes. Smoke-free home.
