As you can see from this file, find the file where your loop is defined, then create or copy over the template file for individual loop items to your theme folder. In the example from the link, this would be content-product.php, located inside the /plugins/woocommerce/templates folder. You can then fully customize the file to your needs.
You can also use the woocommerce_before_shop_loop_item hook to add details to the loop item.
