I agree with antonis12, Appearance.tv would 'fit' a beauty site very well. Being a .tv, it would need to focus on interactivity or some visual stimulus more so than a typical banner/text ad site.
Say, a model that adapted to hair styles/colors that you chose, and the various skin doogies that women use, so people could check the look before they buy. Maybe, short videos of runway models, so people could see apparel in use before they buy.
Undeveloped, not much money, because it would take a fair amount of work and bucks to pull off. Developed, could be a really nice sale.
