Gisele Bundchen in Vanity Fair

I’m starting to wonder, at least in Gisele Bundchen’s case, what exactly is the point in being a model? If I can recall correctly, it was mostly to sell clothes and products. If that is correct, then what exactly is going on in Vanity Fair? Just about every picture is with her wearing no clothes, or is in the process of taking them off. Don’t get me wrong though, I’m not complaining…
