Now is the time to start getting your nails into tip-top condition because the forthcoming nail trend for next season is completely unforgiving. Double colours involves wearing one shade on the body of the nail and another, contrasting shade, on the tip. I love the idea of OPI Black Cherry Chutney (a deep wine-y red) with shimmering grey My Private Jet, but basically, anything goes; red and gold will look ultra glam and for a cheeky twist, try blue and green. You’ll need to stock up on handy stickers called French Manicure Tip Guides (they’re cheap and cheerful from any basic beauty supply store) unless you are remarkably talented free-hand! I’m using the amazingly effective Avoplex Oil to strengthen my nails and tame my cuticles, because the two-tone trend needs immaculate presentation. I’m still not quite sure how well this look can be done at home, but I love the idea so will practice hard!
