Maintenance DoT elastic size?

Hi, I'm not sure I'm writing this in the correct area. I've never been good when it comes to forums.


I have two Dream of Doll, dolls that I purchased back in 2006. The cords (? ) are super loose. I was wondering if anyone knew what to use for them. The website I bought them from is closed and I'm having a hard time trying to figure all this out. From that website, the two dolls I bought were considered teens? I'm hoping someone can help. Thanks!
