Personally It depends on the person. Some people can pull off Tats and multiple peircings and others cannot. For example You must login or register to view this content.
But for the most part you will be less likely to get high paid jobs and it may be something you regret later in life ie. Tattoo sleeves. Saying this, smaller tattoo are perfectly viable as are limited ear piercings. And if girls want to get non visible piecring then I'm fine with that :pedo:
