Demographic Due Diligence: Need Help with My Target Audience

by Debbie.
(Kansas City, Missouri USA)

I know who my jewelry demographic is so here are my questions I need help to take the next step:

Where do I find information on how to market to them?

 Where do I find out information on what they like?

 How do I find information on where the best place is to sell to them?

Any information  would be greatly appreciated. Thanks!
