Glorious tulle gowns create drawing-room drama. From left: The snug ivory lace bustier with off-the-shoulder lace sleeves comes to feminine fulfillment in a crinkled organza A-line skirt and sweep train, about $2,500, by Cymbeline. Choker, by Carolee. A strapless ivory silk-tulle ball gown is highlighted with the season's major accent—a velvet ribbon sash—and a hand-painted champagne ombré hem, about $5,400, by Vera Wang. Multicolored beaded floral embroidery details this lace-up corset, which is paired with a full tulle skirt, about $1,100, by Oleg Cassini exclusively for David's Bridal. Feather comb (pinned on top of bodice), by Leah C. Couture Millinery.
