Forget shoes and bags. The accessory you need to invest in next season is a scarf. They were perhaps most prolific at Burberry, where barely a look hit the runway without some kind of painted silk scarf topping it. At Temperley, scarves and capes became interchangeable, slouchily layered up in china blue knits. Osman used them all over the body, as belts and ties as well as around the neck.
