I've seen some beautiful pictures of Renee Fleming and her amazing dresses, designed specially for the gala showcase by Karl Lagerfeld, Christian Lacroix, and John Galliano. A dress trimmed with lace from "Manon," designed by Mr. Lagerfeld is really a dainty work. Costumes from "Traviata" designed by Mr. Lacroix are iridescent and full of air. And my absolute favorite, the amazing dress, designed by Mr. Galliano for scenes from "Capriccio."
