It's the DOL milky planet replica. They were made in set sizes or custom-size. They were pretty much the go-to back when your only option for cheap lolita was Bodyline, and plus size options were nearly impossible.
So no, it's not cut up like that. It probably is made to fit her. But you can tell it's a replica due to the bow shape, fabric drape, and the lace.
One day, you will become seasoned, newfriend.
