Autumn 09s biggest nail news is the matte top coat. Add this to any colour already in your arsenal and youll be right on trend all season. The latest colours are forest green and midnight blue, but in a break from winter tradition, neon shades look set to stay through Christmas and beyond. The choice then has never been broader, (remember when there was only Chanels cult Rouge Noir?) so whichever look youre going for you can find the perfect nail shade to wear with it. Feeling a little glam-grunge? Then choose navy or forest green to wear with OTK boots and laddered tights. If youre more Olivia Palermo than Alice Dellal, then give mink and grown-up grey a go. Finally, for the party season channel Londoner Lily Allen and go glam-rock in paint box shades and metallics. Click below for ELLEs new season favourites
