Hello!
I have bought Basel theme twice, I love it!
But I have a problem with configuration of shop and product layout: image is not the right size.. they must have the same size, also the thumbnail are out of size. https://caal.it/shop/
You can se also relate product in this page https://caal.it/prodotto/velo-omerale-agnello/
The best way to solve this problem is to upload all images in the same proportions. Otherwise, you can enable Hard Crop for WooCommerce images in WooCommerce -> Settings -> Products -> Display.
