You may want to set up a Copyright © message to appear on all pages on your boutique.
Generally speaking the contents of each page will automatically be copyrighted as a "Literary piece" with the creator - that's you. Some sites add a copyright message in the footer of the site to re-inforce this idea.
You can do this by:
In your back office:
1. Go to Shop settings > Pages
2. Create a new page and call it "All rights reserved 2012 ©".
3. Add any text you wish to appear when someone clicks through on the link.
4. Once saved, re-sort the page position in the pages list by dragging it into the last position.
The page will now appear as part of your shop navigation on every page.
Depending on the theme you have chosen the link will either appear to the left of the page or in the footer links.
