Almost every tattoo you have ever seen belongs to one of a dozen or so styles, and knowing which one you are after is the single most useful thing you can bring to a shop. It narrows the artists worth talking to from every tattooer in Puerto Vallarta down to the handful who work in the way you like — because artists specialize, and the best fine line artist in the bay is not the person you want doing a Japanese sleeve.
Each style below has its own page: what it is, what it suits, where on the body it usually goes, how long a sitting tends to run, and what to ask an artist before you commit. When you have found the one, send your idea through and the shops that work in that style will come back to you with a quote.
