Can a model have a tattoo?

A model can have a tattoo, however, a tattoo can be a complicating factor (although they can be airbrushed out of a photograph if they are not wanted). Your particular tattoo may or may not go well with whatever clothing your are moDELLing, or whatever effect the photographer is trying to create. If a tattoo is needed for a particular photo, they can always give you a temporary tattoo. And that way they can have the exact tattoo that they want. So I advise against getting any permanent tattoo.
