A feline-inspired wing is one of the oldest make-up tricks in the book, but mastering it is no mean feat – the skill is one that requires a steady hand, patience and the perfect tool. Fortunately, our eyeliner collection hand-picks the best in the business, from cult-status names to MUA favourites. When it comes to the first port of call, it should always be finding a fail-safe format. Liquid, gel and felt-tip eyeliners are great for mapping out a ruler-straight line, while pencils can be diffused for a more soft-focus finish. And if you’re looking to stay on the right side of the lived-in look, consider hedging your bets with a waterproof formula.
