This grey Olivia von Halle Gia London silk tracksuit is spun with a touch of cashmere. It includes a top with a drawstring hood and long sleeves, and high-rise track pants with side slip pockets. Both are framed by finely ribbed trims. It'd only make sense we'd get this Olivia von Halle set as we already live in London. But let's be honest, we love to take a bit of the city with us everywhere we go.
