Sies Marjan's collections focus on color and the feelings they evoke. This 'Farah' tote is made from crinkled-cotton canvas that has a cool holographic finish - flashes of ultraviolet and blue make it impossible to miss. It's roomy enough to stow larger essentials such as a tablet or hardback and has a pocket to keep your phone within easy reach. The malleable shape means it can be folded and carried as a clutch.
