Hi Katelyn,
I'm new to Etsy, so I'm not sure I can give you any helpful advice. The photography is great and I wish I knew how to do it as well as you. I'm wondering if you could put more of your items in context? Your models are a good start. Who would wear your earrings? Where would you go in your dresses? Who are your customers? What is the age group? Have you looked at other vintage shops?
I don't know if you are doing anything wrong, but I say keep on changing it up and stick to your dreams. Have you filled out all of the questions about yourself in your profile? It seems a little skimpy. Good luck. Judy
