I am normally a huge fan of Diane von Fursternberg. I have all of her dresses, coats, and many of her pants. This season I fell in love with her blouses and purchased four of them only to discover that the buttons are coming off one by one (namely the Caridad blouses ... image below). I purchased some from her site ad the other from Saks. Anyone else experiencing this or do you know if she made changes to her production line?
