Hi Maria! You have a great shop that's off to a great start. I would say the thing you could work on now is improving your SEO and tags. Your tags should be a mixture of phrases and words - for instance, for this listing:
https://www.etsy.com/listing/110862506/red-mad-men-pin-up-50s-rockabilly-women? I would make your tags: red dress, red coat, vintage dress, vintage clothing, custom dress . . . etc.
Also get a facebook page! It really helps promote your shop. Invite all your friends to like it, and then their friends will see it, and already thats a lot more views and potential customers. Link to your fb page in your policies, about page, and shop announcement :)
Hope these help!!!
