If I had to place a bet, I’d wager that summer inspires the most nail art trends of the entire year. From dreamy vacations to wedding season, there are so many reasons to keep routine nail appointments on the calendar—and the latest trend everyone will be itching to copy this season won’t be nude nails or single polishes. Confirmed by headline-making Chanel runways and Kylie Jenner’s Instagram, summer’s hottest nail trend is ethereal, chromatic, shore-inspired seaglass nails.

When Mattieu Blazy presented his fifth Chanel collection in Biarritz, France—Cruise 26/27, where models cascaded down the runway in a nautical palette of silk, feathers, and fishnet—we didn’t know that we’d also be downloading summer’s top nail trend. Keyed by celebrity nail artist Ama Quashie, the mermaid-like manicures that completed each look quickly became the talk of beauty editor town for the mismatched color stories and semi-sheer, dégradé chrome polishes. Quashie previously told Who What Wear that the key to each look was “finding colours that work by clashing as well as melting into one another,” resulting in a marine-inspired kaleidoscope that both minimalists and maximalists can appreciate.
