Anne-Catherine Frey, before Guy Laroche, Paris, February 2012. 
Can't wait to see Anne-Catherine and her gorgeous smile next week in Paris :)
If you are trying to decide what "must have" piece you need/don't really need but still desperately want for this coming winter, consider an intarsia sweater. They are everywhere this season* (at all different price points) and I suspect that you could pick up some really cute vintage jumpers at op/charity shops... which nobody else will have :) I loved this Carven sweater from last season (well, I pretty much love anything from Carven!) on Anne-Catherine and I have some photos of Hedvig wearing it in a different colour as well which I will post soon.
Recreate Anne-Catherine's look (kind of):
3.1 Philllip Lim Digital Brindle Intarsia sweater (love the sheer knit panels on this sweater), Stella McCartney Intarsia sweater, Proenza Schouler Intarisa sweater, ASOS animal sweater with contrast sleeves, Paul & Joe Sister Alaska sweater, or Topshop Aztec motif jumper
Jeunesse Anouk blouse, Elizabeth and James Damien shirt, or ASOS men's style pocket shirt
Alexander Wang Jane shoulder bag 
ASOS Ace wedge ankle boots, Elizabeth and James Peri wedge booties, or Jimmy Choo Mayor leather ankle booties
*but look totally different depending on what else you style the sweater with.
