I'll give you a quick rundown of the Isle of the Lost. It's a prison, where people who did evil, or were thought to have done evil; were locked up for eternity. Sealed in with a magic barrier that prevented them from leaving or from using magic. Fast forward a bit and they have kids.
The country of Auradon didn't care. They just sent over their trash to the Isle and that is what the kids ate. There were broken toys they got to play with if they were lucky, and any discarded clothes repurposed as best they could be.
If you are from the Isle you didn't even get hand me downs, you get the stuff that no one else wants because it is broken, rotten, or damaged.
