How to parent one cloth to another cloth.

I need to parent one cloth to another cloth for my player mesh. My player mesh has a dress with frills at the edges that are a separate material. I can apply a clothing modifier to both materials but they are separate from one another. Is there a way to parent them to each other or link the vertices?

If not, is there a way to use two materials for only one cloth modifier? Last time someone asked this question there was no response. Please let me know if there is a solution. If not, please say so.
