May I suggest looking on sites like eBay for a second-hand pair of those pants? I’ve had surprisingly good luck finding replacement clothes that are barely worn, so it might be worth looking, and maybe setting up an alert so it will email you if a new listing is posted for those pants.
I mean, that was Getty Image’s whole case against Google’s “view image” button. And Getty won that legal battle, so clearly they have some legal ground to stand on, even though most people would think it’s bullshit.
