Always up for a challenge, especially for Miranda's wardrobe, I sat down with needle and thread and began attempting to modify it to make it Miranda sized. I worked until I couldn't see the thread anymore, and then I went to sleep and dreamed of this dress, and finished it this morning. And here's what it looks like.
The modification was a pain in the butt, and ultimately I don't know whether it was worth it or not. I'll play with a few more pieces in the set before I decide whether I'd buy another one and try it or not. We'll see!
