One thing I have learned recently is to make sure you shop title has a short description of what you do. Like (designer swimsuits or handmade swim wear) this also helps if it is add in the first part of you shop announcement as well.
Also check your tags and description to make sure these are mentioned. This will help SEO find you. Think about if you were searching on Google for a swim suit what would you type in.
