If you’re especially observant watching X Factor you’ll notice that the girls’ nails are looking amazing! OPI are delivering some beautiful manicures in super-sparkle and shimmer (and their upcoming Shattered polish that gives a ‘crackled’ effect). Our picks from OPI for ultra-glam, party season nails are Russian Navy – a gorgeous midnight blue with sheen – or OPI Vodka and Caviar – a fire engine red that looks sophisticated and stylish. Ensure that you give your bare nails a good buff first to smooth over the surface for a more even application, and when using dark or very bright shades, always wear an undercoat to prevent nail staining.
