This one is a super sexy underboob tattoo set that has to be on this list! Thanks to Trillyke, who created this Underboob Sims 4 Tattoos CC Set. There aren’t many underboob tattoos available out there for female Sims, but this particular set gives you ten different designs that are not only fun but also creative! What’s more, all these are base game compatible. For more information and the download link, click here.
