It's only natural that last week's news of the upcoming Target and Neiman Marcus CFDA designer collaboration would be followed by an all-out marketing blitz — and now, it's finally begun. First up: this just-released and pretty intriguing behind-the-scenes glimpse at the collaboration's starting point, which, logically, included lots of meetings in colorfully decorated studios and lots of fabric, print, and sketch reviews. The video shows all that, plus offers cameo appearances by nearly every one of the collaboration's key players, including — but not limited to — Diane von Furstenberg, Ken Downing, Eddie Borgo, Georgina Chapman, Robert Rodriguez, Tracy Reese, Stacey Bendet, and Prabal Gurung. See it all below, and keep those eyes peeled for any clues as to what the 50-piece Holiday collection might actually look like.
