If she's buying designer stuff, she has to be buying retail. I've seen episodes when she was shopping via internet for stuff.
Then instead of hiring a great seamstress to tailor things to fit, she just hacks the stuff up, or spanx herself to be able to get into it, has her minions zip her into it and off she goes. We've seen her with torn, shredded seams and busted zippers, dresses she cut into 2 piece outfits to get herself in. All these designers she knows and Kanye knows, does not one of them, other than Kanye's buddy, design and fit something exclusively for her? Even the Valentino stuf
