From the early 19th century until relatively recently, your blues were workwear, not fashion. Today they are a wardrobe essential and a symbol of easy, couldn’t-care-less style. And now denim is not only back as high fashion, but wearing it head to toe is suddenly nothing to be ashamed of. Take the cropped denim jackets with slouchy denim trousers that premiered on Fendi’s runway this season; the Marques’Almeida denim that unravelled in the duo’s signature style; and the deep indigo shirt at Christophe Lemaire that will look perfect with a pair of your old, well-loved favourites.
