After fondling a Miu Miu bag on Saks' first floor, I headed upstairs, where I found this long white gown. Once I realized it was the one Lauren Conrad wore to the MTV Movie Awards just weeks ago, I couldn't resist trying it on. The floor-length, strapless dress fell in draping layers to one side—very old-Hollywood. The tight bodice enhanced my cleavage—I certainly looked glamorous. Unfortunately, I don’t have a lot of opportunities to wear a black-tie gown. 611 Fifth Ave., nr. 50th St.; 212-940-4176.
