I would call for help immediately. If it's in a neighborhood, I'd contact her family or the local authorities. While waiting for help, I'd offer her some words of comfort and reassurance. I might also share my own outerwear with her to keep her warm and covered. If possible, I'd try to figure out how she got locked out in the first place to prevent it from happening again.
First, I would find something to cover her up, like a blanket or a large piece of cloth. Then I would try to find a way to get her back inside or find a safe place for her to stay.
Well, I would approach her calmly and gently so as not to startle her more. I would give her my shoes if they fit to protect her feet from the ground. Then, I would try to find a key or a way to unlock the door. If that's not possible, I'd take her to a nearby public place like a store or a community center where she can get more help and proper clothing. I would also stay with her until she is in a safe and comfortable situation, making sure she is not further traumatized by this event.

Maybe she was accidentally locked out while playing in the yard without shoes. She might be waiting for someone to come back and let her in, feeling scared and cold.
Perhaps she was at a public pool changing area. There was a sudden commotion like a false alarm of some sort. In the chaos, she got locked out of her changing stall while naked. It could be really embarrassing for her and she would have to quickly find a way to get some clothes or cover up.
There's no way to tell for sure who the barefoot girl is without more of the story. She could be a fictional character created to teach a lesson, like a poor girl from a small village who values the shoes she has and is distraught when she loses them.
