My nail tech started with a milky base before meticulously painting on detailed fish and clam shell motifs (you can choose any of your favorite sea creatures), then she used builder gel on the remaining nails to create an opalescent finish. The final touch was tiny pearls that pulled the entire manicure together for a set that looked as stunning as the Côte d’Azur coastline—it was truly tragic when I had to get them removed.Euro Summer-Inspired@vanityprojects@akikonails_nycA Euro summer manicure complete with your favorite summertime produce, beach towel-esque stripes, and Amalfi-inspired patterns is the ultimate way to lean into the sardine trend. “Whimsical nail art combining green olives, lemons, and tomatoes has been popping up all over social media, showing inspiration from coastal cafes and oceanfront restaurants,” explains Taurua.Add Cosmopolitan as a preferred source in your Google search results.Use your Google account to add this to your settings.Silver Swimmers@swaknails@byjessicaalicex“Most people jumping on the trend go for a minimalist milky or neutral base manicure with playful silver fish,” explains Taurua. For the true brine lovers, you can add a few tiny olives to your nails for a salty look that pairs perfectly with some tinned fish, a charcuterie board, and dirty martinis by the sea—aka my ideal girl dinner.Color Bait @akikonails_nyc@vanityprojectsColorful mix-and-match sardine tips look like the kind of coastal souvenir you’d bring home from a beach vacation.
