These tattoos are uncommon. People generally get a thigh tattoo because it is easy to hide it. There are many places, especially organizations where tattoos are not allowed, so tattoo lovers opt for locations like the thigh where the tattoo can easily be hidden. This is one advantage of a thigh tattoo, however, there is one major disadvantage also. Though a tattoo is a permanent thing, it has a tendency to sag. So if you get a thigh tattoo done, there are high chances of your thigh tattoo sagging if you gain even a little weight. But on the other hand, thigh tattoos also have a long life as they are hardly ever exposed to the sun. So there are both advantages and disadvantages of these tattoos, thus one should think at least twice before getting one.
