I don’t know about you, but sometimes seeing a metallic dress makes me want to shout, “Cocktails?! Cocktails?!” in the Las Vegas-waitress singsong tone. But these elegant frocks are not of your Caesar’s Palace cocktail-waitress variety. More genuinely cosmopolitan than The Cosmopolitan, they are meant for drinking cocktails, not serving them.
