Black cocktail dress, slimming fit

I've worn this dress only once, so it's in near perfect condition. The bunching looks weird on the hanger but it's super slimming and forgiving once it's on. It hugs your body but the gathering makes it very comfortable and forgiving. I'm 5'5" and this dress hits me just above my knees. The satin look of the fabric is shiny but not too over the top.
