Instagram has given us many a fab nail trend, from marble manis to half moon stunners, but we must admit that the latest one, which is straight out of NYFW, has taken us somewhat by surprise: introducing the fine art of nail contouring!

Though traditionally reserved for makeup, this new, for-your-fingers incarnation of the popular technique first showed up at the Chromat Fall 2016 NYFW show back in February (pictured above). Now, a new take on the trend is taking off after popping up at the Vera Wang SS 2017 show courtesy of Jin Soon Choi.

Making the rounds on social media, this hack sees fashionistas making their nail beds look thinner and longer with help from nothing more than their polish.

Whereas Jin opted for a dark stripe of polish down the middle of her nail to create the illusion of a smaller bed, the trend actually comes in two incarnations. Basically, you can go dark on the inside and light around the edges (either leaving your natural nails exposed at the sides or opting for a lighter color), or you can do the reverse.

French beauty pro Pierrick Beringer was way ahead of the fad, posting his expert use of black and white Essie polish to pull off the trend a whopping 84 weeks ago.

But contouring is by no means reserved to neutrals. @NailTheDay, who gushed “I love nail contouring!” took things one step further by playing with complementary hues of blue, placing a darker shade right at the cuticle and covering the rest with a lighter tone: The sky’s the limit when it comes to color combinations!

No matter what color you choose, however, the biggest draw of nail contouring lies within the ability to change your nail shape in a flash, without the need for press-ons or hours of filing.

Chic results for half the work? Consider this one beauty hack we can get behind!
