Ivory underdress/night gown

I am selling my worn ivory/cream dress/nightgown that has been worn to 3 conventions in my Akatsuki no Yona cosplay, I recently bought a better under dress for the outfit and no longer need this, it has a small pinkish stain on the back, barely noticable, I did a zoom in on photo three. The dress is washed but the stain did not come out sadly. :( The dark long thing on photo 2 is just my hair I forgot to tuck up front lol! the tag is listed as size small but it is a dress imported from India, so sizing is a bit different, I am 37in bust 30in waist and 5"4 height. I'm a USA women's large so I'll list this as such.
