For sculpted lips, James recommends prepping them with L'Oréal Paris Touche Magique Concealer (£6.99, boots.com), then using feathery strokes to line the outer edges (try Estée Lauder Double Wear Stay-in-Place Lip Liner, £15, esteelauder.co.uk). Use a lip brush to apply the new Rouge Dior Haute Couleur Lipstick in Ara Red (£22, selfridges.com). For the ultimate latex look, finish with a slick of L'Oréal Paris Glam Shine Reflexion gloss in Sheer Grenadine (£6.99, as before).
