If you head backstage at any Fashion Week show, among the chaos of fablas people fuelled by #fashun pastries and coconut water, you'll find little teams perfectly painting the hottest nail looks around. From on-point manis by Sophy Robson at House Of Holland to the epic designs from Marian Newman at Vivienne Westwood (that's 29 models, 29 completely different nail looks!), London Fashion Week was the place that got it so, so right. Here are four of my fave looks that will take nail varnish doodling to the next level, next season.
