This isn’t a WooCommerce issue and it belongs in the Fashion Stylist theme support forum.
I’ve looked at the code for Fashion Stylist and it looks like the theme author has not provided a template hook into the code to enable the footer to be modified easily.
You could create your own child theme, a copy of Fashion Stylist, then modify the function blossom_fashion_footer_bottom() at line 625 in functions.php. That would fork the code so you would not be able to take advantage of future updates to Fashion Stylist. PHP skills would be needed.
If you edit functions.php in Fashion Stylist directly, that would work but you would need to make a note of your edits and remake them every time Fashion Stylist gets and update, since updates would override your edits.
You could ask in the theme support forum:

The parent theme, Blossom Fashion, is constructed much better and the footer code can be intercepted and changed. You would make your own child theme with your modified copy of blossom_fashion_footer_bottom() in functions.php of the child theme. Again, PHP skills would be needed.
For a non-PHP solution, you’ll need to look for another theme with more customisation options.
