For purchasing:
I have no idea as to one single store, it's honestly just a search and buy mission for this kind of stuff.

It's wonderful you've decided to try a '20's inspired look. Keep in mind that there were many different looks back then, so you can really work with many different styles. Good luck and have fun!!
