Holly, what your picture is missing but the vintage one has is the rim light. It's not as obvious because the picture is not as shadowy, but you see highlights in the hair, shoulder and cheek, all on model's right side. I'd use a small head fitted with a 30 or 40-degree grid for this, but aluminium reflector with barn door would also work. If the light is too specular, you can always use light tough frost gel. Color fade, color crossover, outfit, hair styling, makeup, etc. have already been mentioned.
