Sometimes, the biggest impact for a mani is when there’s nothing there at all – welcome to the concept known as ‘negative space’. To copy Lou’s nail exactly, you can either paint the entire surface in a bright orange –  then use a cotton bud saturated in nail polish remover to wipe and create a gap. Or, if you have steady hands, paint the colour on, leaving a stripe down the middle. Then use a white polish, such as Essie Nail Colour in Blanc (12.3ml) to frame the space either side of the bare section of the nail – and you’re done.

It’s time to channel your inner Picasso for this one. Begin by painting a soft pink on the nail. And then take the brightest colours you have and paint thin stripes from the tip down, at varying lengths. Precision not required!
