This was one of my fav looks from Australian Fashion week: it is laid back, effortlessly stylish, entirely wearable*, subtle, beautifully accessorised (love the Alexander Wang leopard wedges and her necklaces)... with just a hint of peek-a-boo-black-lace-bra sexiness thrown in for good measure. Helps that she is entirely gorgeous, of course!
*obviously if you don't work in a fashion office the visible underwear might be a look you will want to keep for weekends only :)
