Hi Diana,
If your tags are using words and phrases that you have in your titles then they are fine. Personally, once I've set up a listing I rarely adjust the tags.
One thing that you may want to do is update your shop title to reflect more accurately what it is that you are selling. I'm not sure how many people search for 'Be Unapologetically Original ' when they are shopping and the title is an important part of being found through Google.
You may also find that you need to do a bit more marketing directly to your target audience as well. I've found that if I'm reaching my target customer with my marketing that my sales continue to grow.
