When it comes to nails, navy is the new black. I think there's something so chic about glossy, deep navy nails and 'One Track Mind'* from China Glaze is just the right shade of blue. Not so dark that it loses it's navy-ness, but dark enough for that autumnal sultry sophistication. This is the first China Glaze polish I've ever tried, from the wide selection at nailpolish.co.uk, and on first application I found it a little thin and hard to get a solid, opaque finish. But after a good shake and a little bit of getting used to working with the consistency, you can get a nice full coverage in two coats.
