Elegant black evening/prom dress

I bought this from Dillard's for $100 and wore it once for prom. It says a size small, which could fit from a size 2-4. Sort of stretchy black material with mesh details on chest and down the sides of the thigh area. There is material behind the mesh on the sides that cover hips to mid thigh region. There is a slit on the left side to show off some leg. It zips up in the back with a gold zipper. Willing to negotiate price but please be reasonable. I need money for school clothing this fall.
