Couture should be viewed as art, as sculpture. It is pointless to justify it's use and wearability! just worship the clothes for what they are in the same way we look at art, Couture is a porthole into the mind of the worlds most imaginative people.
Elie Saab is a prolific designer. His runways have about 60 outfits each. Some are simple, some shiny, but all of them are great eye candy. I've gone through and picked my favorite looks, and ironically, there are exactly 60 of them.
couture should be worn on the red carpet -- where else can you get away with miles of whipped organza, gem-studded bodices, and fabric shinier than the glean on a statuette? these stars know that ready-to-wear is for runners-up.
