Lily Allen pairs party dress with a set of simple-but-statement nails Singer Lily Allen made a return to the red carpet in a monochrome Chanel gown, offset with fluorescent yellow nails If the words 'party accessories' are enough to make you itch and squirm, take lead from Lily Allen's novel approach - spotted last night at the London premiere of Disney's Saving Mr Banks. Instead of piling on a ton of awkward bling, the singer chose a single statement piece to embellish her monochrome Chanel gown: a set of 10 super-glossy fluoro yellow nails. SEE: Manicure of the week Here's what made the look work: The elegant elongated almond shape of the nails (no stumpy broken ones or boring short squovals) The pristinely painted polish: fresh, shiny and chip-free The bonkers colour against the sober black background, making it all just the right side of punk without veering into teenage territory. While neon yellow might not be up your street, any flawlessly applied hot-hued tips vs LBD works for all ages as a clever way to say 'yes, I can be fun and make an effort!' without resorting to dingly dangly sparkly silliness if jewellery isn't your thing. So stretch out your winter nail polish roster with the following colours or spend your accessory budget on a couple of good manicures instead.
