How to add a border to product images in Squarespace 7.0

Hello,

I am trying to add a border around the images of my products in the store. I have tried using

.tweak-product-list-meta-position-overlay .ProductList-item {
    border: 1px solid black;
    margin-left: -2px;
}

and a couple variations of that to no avail.

A nice to have as well would be to add the price and name of piece below the product, within the border as well.
