J. Crew quilted down jacket L Large olive green

Such a classic staple piece for fall/ winter! J. Crew belted quilted jacket in an olive green with gold tone snaps for closure. Overall look of Jacket is great; however, upon close examination, there is a dark rubbing stain on the inside of collar. I am unsure as to the origin on stain or whether it could be removed (see photo). There is also a faint watermark type stain on one pocket.
