Leave it to Lady Gaga and Rihanna to rock a 1970s trend and make it look cool again. In the past couple of years, we've seen an outpouring of exploratory nail styles. Everything from metallic colours, to neons, primary's and basics have made a resurgence. I've always been partial to a square nail with rounded sides, or a traditional oval nail, but this look reminds me of a stiletto shoe; sexy, daring and dying to be noticed, so it's no big surprise that Lady Gaga and Rihanna are leading the trend. Would you ever rock pointy nails in real life?
