"Diamonds Are Forever" was the theme song Elie Saab had in mind for his Spring couture show. It wasn't literally on the soundtrack, but the entire collection was based on the sparkle and color variations of the world's most expensive rocks. It certainly looked as if he'd invested in a mine of silver sequins and crystalthey were lavished on every number: sprinkled over tissue-fine silk, chiffon, and satin; smothered over bolero cardigans; and clustered in chunks on bustiers. The cumulative impressionall those flouncy skirts and body-line siren dresses, the pastel pinks, blues, yellows, and violets and trimmings of ostrichcalled to mind Dancing With the Stars. (Well, let's not forget it's a TV hit all over the world.)

The audience was packed with clients who visibly appreciated every minute.
