Styling a single product border on product page

Site URL: https://www.caferoyalbooks.com/shop

Hi, I'm using Brine, SS 7.0. I have a product page and I'd like to add a box shadow:

 .ProductList-outerImageWrapper {
  box-shadow: 2px 2px 3px !important;
}

BUT...I want to exclude some products from this style. Is there a way to style individual products on the products page? I have the yui code but not sure if that's how?

Thanks

@creedon that's amazing! thank you
