Interestingly, the study did refute an earlier finding about women with tattoos. In 2007, researchers from the University of Liverpool showed that men rated women with tattoos as physically less attractive, but sexually more promiscuous than those without. In this study, researchers found that physical attractiveness—as rated by the men on the beach who agreed to answer questions about the woman—wasn’t impacted by the tattoo. Another study in 2005 also found that tattoos don’t change attractiveness, but do negatively impact a person’s credibility, regardless of their gender.
So tattoos might not be bad for picking up dudes at the beach, but they might impact what those dudes think of you in the long run.
