Can you please give us a live page to check it out? I can't see it, for example on this collection page the picks looks to have the right ratio: https://www.freethespirit.ca/collections/underwear
In addition to the link that Mircea is asking for above I'd also suggest that you leave:
I also don't see any issue with images beign squished so it's possible that you've fixed this aleady.
You can change that image to have the same ratio as the rest or go trough your JS files and see what is placing that style attribute and remove it. You can check also in your theme settings if there is something that reffers to image ratio and dissabel it.

Our images on the following pages used to look perfect but now are looking stretched, how can I reverse this?
