Navy Mackage Down Puffer Parka, with hidden hood

Bought this from Mackage.ca for $690 + taxes. Size: XS Special features: Leather trims, hidden hood, detachable sleeves. Only worn a few times, and have been kept in a dust bag ever since. Nothing wrong with the the coat, I simply gained weight and this coat is now too tight on me. Comes from a smoke-free and pet-free home.
