It's no secret that over the last few years nail art has gone mainstream. What started as a niche look that most of us couldn't pull off has evolved into something so popular that women of every age -- even dedicated Mademoiselle-wearers -- are giving it a go. And really, what's classier than chic nail designs?

Like so many trends, this one began at Fashion Week, and it continues to gain momentum and evolve backstage. Virtually every polish line (think Essie, Creative Nail Design, and Deborah Lippmann) is now represented on the runway. The artists work with designers to create unique nail styles to complement the collections -- and a lot of the manis receive as much attention as the clothes.

Backstage at the shows, the scene is usually beauty mayhem with hair extensions flying, glitter powder in the air, and row after row of press-on and acrylic nails. But the most recent Mercedes Benz New York Fashion Week was a little different: A lot of the nail art was done by hand, and many of the looks were original and attainable.

See 10 nail art ideas you'll want to try now.

While we wouldn't call the latest trends easy, they definitely require fewer tools and less time than you might imagine. You just need to stock up on polish, steady your hand, and grab some toothpicks to make a go of it. Whether you're an expert looking for inspiration or a beginner just wanting to mix up your mani, here are 10 nail art ideas you'll want to try now.

Difficulty Level: 7 (out of 10)

We spotted these swirly, psychedelic nails backstage at Nicole Miller, and we were truly entranced. CND's Wanda Ruiz used bold shades (Plumville, Electric Orange, Bicycle Yellow, and Anchor Blue) to create the look, which she says you can easily do at home with a few toothpicks. "Dip a clean toothpick into whichever color you want to use first," she says. "Then, start in the center and drag it along the nail creating a spiral." Because the toothpicks are rigid, you'll have more control than if you were to use a detailing brush. Just keep in mind that this mani is going to require a serious amount of patience and may take a while.

The hand-painted flowers at Rachel Antonoff were inspired by one of the prints in her collection. If you want to try to copy this look exactly, start with two coats of CND's Flashpoint; then, working with a detailing brush, paint a fern design on the lower half of your nails with Anchor Blue and Brilliant White.

The best part of a look like this one is that you can mimic any floral in your own closet. If you've never attempted something this difficult before (or if you're not ambidextrous -- since applying any polish with your non-dominant hand can be difficult), try painting a set of artificial nails instead of your own.

Difficulty Level: 3

To get the look of intricate nail art without using a brush (or polish for that matter!), look no further than Minx, a line of foil-like stickers that adhere directly to your nails. At Calla Collection, Minx created a custom print to match a swatch of fabric from one of the looks in the show. While this particular splattered print isn't available, Minx has a selection of similar designs you can try. Then, all you have to do is smooth the stickers onto your nails and file away the excess.

Difficulty Level: 2

From the clothes to the accessories to the nails, gleaming metallic hues were all over the fall runways. At Behnaz Sarafpour, CND's Roxanne Valinoti used gold and silver polish (called Gold Chrome and Silver Chrome) to give the models a "high-tech, feminine" feel. "It looks so special, but it's easy to do," she says. Use two coats of a metallic polish and top it off with a shiny topcoat.
