flappers of color

I recently read Flapper, by Josh Zeitz, for my American History class, and came to the realization that the lives of flappers of color is a topic that is ripe for dissertation-type research.

While I find this incredibly interesting, I'm not immediately drawn to it as a research topic for myself because I haven't yet found a connection to the law.

Unless it would be the relative freedom that women of color had to embrace a flapper lifestyle because they were not bound to the virtue of white womanhood... but is this a real legal freedom or simply a cultural freedom?

That's the initial research question, I suppose.
