A growing trend in the US and UK is to place artistic titoos over the surgical scars of a mastectomy. "More women are choosing not to reconstruct after a mastectomy and tattoo over the scar tissue instead.... The mastectomy tattoo will become just another option for post cancer patients and a truly personal way of regaining control over post cancer bodies and proving once and for all that breast cancer is not just a pink ribbon." The tattooing of nipples on reconstructed breasts remains in high demand, however.
You can also go for portraits of fictional characters considered by many as a badass. Examples of which include Tyrion Lannister (Peter Dinklage) from Game of Thrones, Darth Maul (Ray Park) from Star Wars, the T-800 Terminator (Arnold Schwarzenegger) from the Terminator films, and Blade (Wesley Snipes) from the Blade films. Be sure that the tattoo artist is well-experienced in the portrait department, though.
Hamlet says it's common for clients to ask for a few changes here and there after the design is done — but recommends going into the process knowing that you shouldn't micromanage the whole thing. Give your tattoo artist the leeway to be creative and use the artistry that is his or her forte. On that same note, don't be afraid to ask for something different if you don't like it. Hamlet says he works on a design until everyone is happy with it.
The word tattoo, or tattow in the 18th century, is a loanword from the Samoan word tatau, meaning "to strike". The Oxford English Dictionary gives the etymology of tattoo as "In 18th c. tattaow, tattow. From Polynesian (Samoan, Tahitian, Tongan, etc.) tatau. In Marquesan, tatu." Before the importation of the Polynesian word, the practice of tattooing had been described in the West as painting, scarring or staining.
