If the manicures we saw on the Spring 2015 runways at New York Fashion Week were any indication, nail art is here to stay and basic polish is so last year. One of the most notable and Insta-worthy designs we saw incorporated negative-space—the space on your digits that's either not covered with polish or contrasting with another design. Gotham is bursting with cool-girl nail salons that are capable of creating the trend. So, we're highlighting a couple of our favorite joints (via their Instagram accounts) that just, well, nail it (pun intended). If you want flawless fingers that are begging for a glossy-magazine close-up, let these technicians file, shape, buff and paint your nails into a modern masterpiece that's totally MoMA-worthy.
