Love is in the air for Chicago partygoers, and it’s showing up in the ultrafeminine sweetheart neckline. The curve-hugging cuts of the gowns featured here add drama to typical gala wear. Whether in cool colors or the season’s radiant red, the neckline highlights decolletage, so simple necklaces and bare skin look best. Swept-back hair or a stunning updo can help accentuate a long neck, while cascading waves add awards-season glamour. Match the gown with a shining smile and you’ll be the sweetest thing in the room.
