In June 2015, Reinhart debuted an arrow tattoo on her left forearm. She revealed to PeopleStyle in 2017 that the ink represents her journey with anxiety and depression, and is meant to serve as awareness to take care of your mental health. The actor quoted the mantra, "An arrow can only go forward by belling pulled back," as her inspiration.
What's more, the Riverdale actor realised in 2016 she and her on-screen mother have the same tattoos on the same spot of their arm, by the same artist (celebrity tattooist Dr. Woo). "Mother-Daughter telepathy?" she asked on Instagram. This is one of Reinhart's most noticeable piece of ink.
