There's a new Mayle coat (sz. 6) up for sale on eBay, starting bid $299, she says she paid $790, which I can believe. The ivory collar and sleeves are attached to the plaid coat. I'm not really sold on the back, but that's not the best pose, either.
Update: my APC black peacoat is now sold out. So much for the cheap option.
Mayle coat on eBay: I think it'll sell for $450. That is, if anyone is willing to start off with such a high bid.
