Confession time: I'm one of those people who got a tattoo when she was younger and grew to regret it shortly thereafter. (What can I say? I'm impulsive.) So when I first started seeing metallic temporary tattoos on the music festival circuit and at the beach, I was enthralled. There are now dozens of designs of these shimmery gold, black and silver tattoos in every pattern you could want. These metallic tattoos can be worn as body art or eerily realistic-looking jewelry. Most products last four to six days and rub off with ease using coconut oil or baby oil. And each tattoo comes on a sheet with multiple styles, so you can cut up the designs and remix them however you like.

One half of the design duo Caitlin McCarthy and Caitlin Murray, of Caitlin + Caitlin Design Co., wears Flash Tattoos as eye-catching midi rings. (We're equally obsessed with her foil nail decals.)

Alessandra Ambrosio's feather Flash Tattoos had everyone buzzing at this year's Coachella festival. The temporary tats (from the Sofia collection) are perfectly in sync with the model's signature boho style.

Flash Tattoos were originally designed to resemble jewelry. These wraparound Flash Tattoos are perfect for creating glimmering sets of faux arm candy. Plus, technically you're shopping for charity -- five percent of the proceeds from the Goldfish Kiss H2O collection go toward Waves For Water, an organization that provides clean drinking water in impoverished communities. Purchase, justified.

Miami Swim Week is the place to be if you want to infuse some fresh ideas into your beauty routine. (Check out all our favorite looks from this year's shows here.) L *Space by Monica Wise sent models down the runway with these mermaid-like metallic temporary tattoos.
