I just bought a shoulder Gaucho (the one with the zipper on top) two days ago in Off-White.. I just fell in love with it.. however, I was really choosing between off-white and black because black seems to be so much more durable. Does anyone know whether off-white color is hard to take care of? I would really hate to see it get dyed with jeans or dirty since I love it so muchl.. please help me decide! thanks!!!
