The beautiful Marilyn Monroe is still loved by many people. So much that they get tattoos of her portrait on their bodies. I have seen some really amazing ones. A tattoo like this would require an artist who does portrait work really well. In color or black and grey, it will look amazing.
Many people love the Christmas season so much that they get tattoos inspired by the holiday. I have seen everything from Santa, snow, The Grinch and more. Men and woman have gotten these awesome tattoos. Just try and be original. Get a good artist to do it.
