Every year, a select handful of tattoo designs end up flooding the mainstream. You don't have to be a rocket scientist to figure out that social media is the main driving force behind the proliferation of these inspiring forms of body ink. So, here's a rundown of the most popular tats of 2015:

1. The "Infinity" sign

This tattoo is a keeper. The infinity sign is a huge hit with the ladies and is usually rather discreet in size. The tat is often combined with a heart or the word "love" (for undying love) or with birds (representing the soul of a deceased loved one, for instance).

2. Arrows

Arrow designs of all shapes and kinds were blistering hot picks in 2015. This year, most tattoo artists got requests to do tats like these at least every week.

3. Watercolor tattoos

Watercolor tattoos can either be permanent or temporary. They stand out for their bright colors that can fade beautifully into one another, and they are most prevalent in the summertime.

4. "Underboob" tats

Yep, you guessed it! "Underboob" tattoos are inked right under the bosom. Barbadian singer Rihanna has been the most prominent trendsetter for this style of tattoo. They are often incorporated with a Mandala design, which is a geometric pattern that represents the cosmos.

5. Temporary tattoos

Temporary tattoos are gaining increasing popularity in the tattoo market. The designs are becoming so professional-looking that you sometimes can't even tell them apart from real tattoos. Among the biggest hits are the gold and silver metallic tattoos. One of the more recent trends is the white lace tattoo.
