Gowns with fluid folds and swagging work wonders for women who want a whittled waist. Precision folds are the focus of this iced-gold taffeta gown. The crumb-catcher top has ruffled detailing; dramatic side draping stars on the floor-length skirt. Rhinestones, crystals, and sequins add sparkle factor. About $1,049, Alfred Angelo. Earrings and cuff, Siman Tu. Ring, Martin Flyer.
