do top department stores even know what they're selling?

Like, what if Jimmy Choo and Ugg came up with this absolutely hideous pair of $600 shearling boots. with embroidered stars all over. you get the picture. that's what im thinking about. So nordstrom/bloomies/saks carries both JC and uggs but wtf would they carry this?? do they have a deal? because that kind of cheapens their image i think! like i would think that macy's wouldn't care but do they get to choose which products to carry and which to not. but i suppose it's fashion, and usually in fashion, somebody thought it was a good idea and put it out so somebody else will probably like it/buy it. And even if it's ugly as hell they put if off as modernesque fashion.
