Utilising materials in unusual ways is one of Etro's signature attributes, with this linen sweater making a prime example. The breathable fabric is rendered into a thick-knit construction reminiscent of your favourite winter-weather piece, complete with a spread collar, but its relaxed structure and lightweight material makes it much more preferable for cool evenings spent overlooking the setting sun after a warm afternoon. How to wear Harrods: Style with chinos, sandals and a shoulder bag.
