Louisa Rose Allen AKA singer Foxes, has cemented our love for boilersuits. Banishing any workman vibes, Foxes dolls up her all-in-one with heavy cat-flicked eyeliner, a metallic clutch and sleek sandals. Don't go thinking these babies only work exclusively with a heel though: trainers and flats look awesome too, as long as you show some skin where your trousers end and your shoes begin. Geddit?
