The classic LBD is a party wardrobe essential, and few are as reliably chic as this iteration from Alessandra Rich. It's been crafted in Italy from smooth silk-blend fabric with a nipped-in waist and curve-enhancing silhouette. The off-the-shoulder cut is suspended by two barely-there shoulder straps and exaggerated by voluminous ruffled trim. Elevated yours with a pair of vertiginous heels for a evening outing.
