Each of Simon Porte Jacquemus' collections starts with an elaborate story - this season's is about an imaginary Parisian It girl. Made from off-white crepe that's woven with touches of wool, this 'La Chemise Paco' top has a cool asymmetric collar, ruffled trims and voluminous ruched sleeves that lead to exaggerated cuffs. Wear yours with simple black tailoring.
