What does a sugar skull tattoo symbolize?

Day of the Dead (dia de los muertos in Spanish) like Halloween, is based on the ancient feast of All Hallows Eve, which is said to be the one night that the spirits of the dead can return to earth. Day of the dead tattoos can serve as a celbration of those who have passed on. They can also serve as a symbol of change, strength, or living life to the fullest.
