The nail art trend shows no sign of abating. In fact, we can’t even call it a trend anymore! Enter YSL’s new line of topcoats, La Laque Couture Tie & Dye. Each can be worn on its own, or layered with polish for a shimmery, crackle-like finish. Check out the three looks we got with the base color Violine Surrealiste, an intense fuschia from YSL's La Laque Couture collection, and its coordinating topcoat, "Hip Coat."
