However, one distinction still remains. The men generally sport tattoos on the upper arm and it really looks macho on them.
Women cannot sport such tattoos because they just do not look effeminate. They generally like to sport tattoos is places where they can both sport them or hide them as per their wishes.
So, as obvious, there is no better option for a tattoo than to wear it either on the lower back or lower stomach. These portions are generally covered and do not show. However, wearing low waists or beachwear can go on to show these tattoos off.
