A quick scroll on Rosalía’s Instagram will reveal acrylics in rainbow bright colours and metallic and faux gemstone tips that she wore to a festival performance in Moroccoin in 2019. She meticulously matches her manicures to her outfits, as she did last month in with an animé-inspired outfit by Korean streetwear brand Skoot. She further enrolled with Miami-based nail artist Kro Vargas to craft a matching set of nails that incorporated the artists’ signature female figures. Her latest manicure combines two unlikely groups of people: acrylic nail obsessives and computer science nerds.
