MM6 Margiela silver coat

MM6 by Maison Martin Margiela convertible silver raincoat. Zipper closure. Can button bottom underneath for it to be short or unbutton it for it to be long. Large front pockets. Tag says 42. Bought from Erdon in Philadelphia, from spring/summer 2013 collection. Missing 5/10 buttons inside to button the hem up(plain white plastic buttons that can easily be replaced, not visible from outside) and is still able to be buttoned up with the remaining buttons. Otherwise excellent condition!
