Fashion: Don't forget your coat

Another season, another must-have Chanel nail varnish. This summer, talons are set to be painted mimosa yellow – a tricky shade to pull off, and therefore one which seems to have found a natural home on the fingertips of the It-crowd. Elsewhere in the range, there are gentle pinks and bubblegum shades – the perfect foil to all the bright, Pantone shades on the catwalks for spring. Les Fleurs d'Eté de Chanel, available now, from £17.50, selfridges.co.uk
