They're called nipples. It doesn't matter if they're puffy, perky, or painted; if they're out, people will pay attention. It's also a good idea to put your name on the model's panties; statistically speaking, that's the next place people look when they see nipples.
Sure, there's a small percentage of people who go from nipples to eyes, but those are the people who are concerned with not looking like perverts, and their consumership is not as desirable. Let's face it: everybody wants the pervert market and no one wants to admit it.
