According to Urban Dictionary, a go-see is when a model is sent by her agency to meet with one of their clients: a photographer, a designer, etc. It's basically like an audition.
Between 1998 and 1999, photographer Juergen Teller received hundreds of models at his studio for various castings and photographed each and every one of them. Later on, these fashion images were published all together into a conceptual art photography book called "Go-Sees".
I'd love to get my hands on a copy, and see all photos. I was able to find some images on tumblr and pinterest, and what's interesting to see is how these girls presented themselves to their first audition. Eventually, some of them got really famous (like Shalom Harlow) and others, most probably never made past the initial photo-shoot.
