Womens dorothy costume

Hand made, I'm 15 made this at home with a little help from my nana. I made a mistake in my size, at first it looked like it wouldn't fit, so I made it bigger and now it's way to big for me. I hand stitched the buttons and the neck hooks. Everything obviously is new and hasn't been worn to an event, just worn to try on and make adjustments. The waist fits abt a large to XL and the rest of the dress fits like and XL. All the time and work Isk if I will negotiate, just message me pls.
