I think you've misunderstood me. the purpose of the site was to have a central social media space that would never go away for people who purchase/like PUG. There is no rule that you must purchase their clothing/goods to be allowed on the page.
that being said, the clothing pictures should be focused on PUG clothing- it's helpful for others who are wanting to see what a specific style and size look on someone who is their size/body shape, hence why the pictures are sorted by size. there are several communities/special interest groups on this website, and a few are dedicated to Vintage clothing (not repo) where posting pictures of vintage digs would be absolutely suitable.
