You could try calling the Chanel outlet at Woodbury: (845) 928-1550, though I'm not sure if they have clothes, or only shoes, bags, and other accessories.
Unfortunately, the outlet will not ship anywhere. I would say eBay is probably your best bet.
whoa, they have it now?? is it on the site? i've been looking for the sweater too.I'm bumping this to let those who are interested know that Topshop has a version of this sweater.
