As the clichéd saying goes, what’s old is new again, which is certainly the case for the half-moon manicure trend taking New York Fashion Week runways! The crescent design first originated in the 1930s and ’40s, as evidenced by Joan Crawford‘s penchant for the pattern, and designers like Peter Som, Lela Rose, Jenni Kayne, and Desigual are giving the look new life by incorporating bold colors and modern finishes. At Lela Rose and Jenni Kayne, manicurists stuck to neutral tones — Kayne’s models took the runway in a nude-on-white combo, while Butter London’s Katie Jane Hughes concentrated the brand’s grey Lady Muck lacquer ($14; at the base of the cuticle for the Lela Rose show. Peter Som’s models wore the blue and green lacquers from his Zoya collaboration ($24 for three;, but the biggest switch-up we’ve seen so far has to go to Desigual, where a reverse half-moon effect was created. “It’s a twist on a French manicure in a circle of color on the tip of the nail,” said lead manicurist Keri Blair, who used MAC’s polishes in Steamy, Fiestaware, and Impassioned ($16 each; on a crisp white base. To bring the runway effect into the real world, we recommend picking up a pack of French tip guides like Orly’s ($5; if you have trouble holding a steady hand. After your base color has dried completely, place the stickers onto the lower portion of your nail, and sweep the second color on top. Make sure to let each layer dry completely before removing or applying the guides — any wet lacquer will get pulled off, which can make things messy.
