Designer gown. Eddy k mermaid dress. Lace embroidery over lay size 16

This dress is a size 16 fits really small. I normally wear 12/13 and I’m 5’9 tall. It has lace embroidery over lay. I bought it bran new and it’s never been altered. Only worn the one time. Has lots of fluff and really beautiful long train. Ivory is the color. Has no stains or rips. I bought it from Mimi’s bridal. I’m asking 700
