Curve hugging elegant gown lowest price

This feels and looks satin but is 100%polyester. It has the criss cross tie in back which gives the size some fluctuating/ its a 7/8 but I would say a true 6. Although,like I said its a curve hugging classy gown so maybe 7/8 would look even better cuz as u can see it's a Lil big in me which takes away the mystique and balance of it all but I still wanted to model it cuz type of gown that's impossible to picture without doing so. There are floral crystals on top.it zips on side. Goes to ankles.
