"No one tells me what to wear," Avril Lavigne once said. And no one expected the rock star to wed musician Deryck Whibley in a stunning cream puff of a dress. The strapless organza princess style—reflecting a return to classic femininity in bridal wear—transformed Lavigne from punk to pretty. These following designs evoke the same mood.

Full skirts—pleated, plain or gathered—are the hallmark of this genre. Off-the-shoulder silk taffeta with full skirt, pintucked bodice and appliqué hem, Oscar de la Renta, $5,800; at select Saks Fifth Avenue stores, 212-940-2269.
