Catherine's Royal Wedding Dress... Prom Dress Trend?

When Kate Middleton, now officially Catherine Duchess of Cambridge, stepped out of her carriage to debut her wedding dress to the world April 29th 2011, everyone from fashion appreciators to couture designers gasped. For years, strapless gowns have been the norm, for prom queens and brides alike. But Catherine walked down the aisle with long, elegant lace sleeves that combine traditional fashion (covering of shoulders in a church) with modern elements (a plunging neckline and a fitted bodice). She also wore a second dress that was equally stunning, a white satin strapless evening gown with a circle skirt and diamante detailing around the waist. Both gowns were designed by Sarah Burton at Alexander McQueen.

Now, the inevitable copycat dresses are going to hit the racks. What do you think- are long sleeved prom dresses going to be in for next year? Would you wear a long sleeve formal dress?
