Tory Burch down satin puffer sleeping bag coat, sample, perhaps ooak?

Beautiful long down coat, scored at a Tory Burch sample sale. Worn less than 10 times but has a bit of staining which I’ve tried to picture, nothing too noticeable (most significant is to the interior trim by the snaps). I don’t think this particular style ever went into production but it’s made of super luxurious feeling satin material and has a real down filling to keep you warm! Size xs/s but could fit a small medium comfortably. 45” from shoulder to hem, 21” ptp.
