When it comes to investment buys, you can't get much more classic than a trench coat and this style by Salvatore Ferragamo is one of our favorites this season. It's been beautifully tailored in Italy from cornflower-blue silk-twill and has leather panels at the sleeves. The scarf-inspired lapels and waist-cinching belt are unquestionably chic. - Cornflower-blue silk-twill and leather - Snap fastenings along front - 100% silk; trim: 100% leather (Sheep)
