The Rolls Royce of Vegas fashion

Noteworthy for: This is Bellagio's fashion row. And it's designer-only, of course.

Clearly, Bellagio is competing with the Wynn for the title of most extravagant shopping arcade. Rounding out the list of exclusive boutiques at the hotel's high-octane fashion district are Giorgio Armani, Chanel, Dior, Fendi, Gucci, Bottega Veneta, Fred Leighton, Prada and Louis Vuitton.

For shiny baubles, silver jewelry (and pretty diamond-encrusted fish, crabs and sea horses) drop in on the classic New York icon, Tiffany & Co. And for staggering opulence and legacy jewels befitting a maharajah, have a peek at Fred Leighton and their museum-worthy collection of art deco pieces.
