Hands, feet, arms and legs, lips, eyes, hair, even parts of the torso – parts models work with just a small portion of their body rather than the whole thing. They may cover more than one part, or focus on just the part of their body which is most attractive. A hand model salary could be very different from a foot model or an eye model, so it is difficult to put a figure on this. It is very niche work and requires hard work, physical discomfort, and determination to succeed – as well as being extremely protective of the part that you model.
