How can I add border-radius to square images in Dawn Theme?

I am having an issue where I can’t seem to find where border-radius needs to be added to convert the square images in the collections to circles.

Ideally I’d like to match the design of Etsy for the catalog. Been struggling with this most of the day and I’ve finally resigned myself to asking for help.

Please halp :heart:

I’ve attached what I am trying to accomplish. If one of you amazing partners can help me I’d be super happy!
