Audrey Hepburn isn't the only girl who's glammed up the windows of Tiffany's. The luxe jewelry emporium just commissioned Rachel Zoe to design the windows of its flagship stores in honor of the 2012 Academy Awards, and the results are SO maj.

The sizzling hot stylist and fashion mogul created windows celebrating Hollywood glamour and fashion from the '30s through the '70s. Rach created five stunning looks – one for each decade – that have been unveiled at stores in New York, Beverly Hills, Hong Kong, Tokyo, Singapore, and London.

RZ joins a roster of artists and designers including Andy Warhol who've taken on Tiffany's windows, and is clearly thrilled to have gotten the chance.  She said of the gig, "To see my interpretation of glamour and luxury unveiled in Tiffany's windows is an amazing experience.  Tiffany is one of the most iconic American brands, and I am honored by this wonderful opportunity."

Rachel used peacock feathers, black glass beads, a vintage vanity, silk, a giant white staircase, orchids, and bamboo to create the period atmospheres.  The 1960s window features a magnificent Jean Schlumberger Fleur De Mer brooch, which was a gift from Richard Burton to Elizabeth Taylor in 1965.  (The jeweler acquired the brooch from Liz's estate.)

She hosted a Twitterchat to talk about the windows and her collaboration with Tiffany, saying, "@TiffanyAndCo It was an absolute dream. What could be more fulfilling than combining the finest jewelry in the world with glam decades?"
