I have no idea the make of this dark green lace and silky material size 20

This restless bought and worn one time for a Christmas wedding. I have no idea the maker of it. I ripped out the tag because it was annoying to me so I’m willing to sell this dress really cheap and it has no holes no rips and has only been worn once time Return It is dark green in color size 20 I know it is right below my knees and I’m 5 five”3
