Tattoos are increasingly becoming a popular form of self-expression for women. Small tattoos on the back of the arm in particular have started to gain traction in recent years, and for good reason. Small back of arm tattoos are discreet, making them perfect for those who want to show off their ink without necessarily making a statement. Plus, the back of the arm is an ideal spot for smaller tattoos, as the arm is a relatively flat surface with lots of space.
