Givenchy creative director Riccardo Tisci has no plans to do a diffusion line for a store like H&M anytime soon. "Maybe one day, yes," he acknowledged at a Givenchy trunk show at Barneys yesterday. For now he's content with the lower-priced capsule collection by Givenchy that launched in Barneys this week. Tisci told Fashionologie he's also in town to "work on an upcoming show in 2011, which I'm doing all the costumes for. I can't say much more, but the performance is a combination of music and opera, and will travel worldwide. A project like this has been my dream." Interesting! Lady Gaga is currently in New York and also working on putting together her "Fame Monster" tour, which she has described as a "pop-electro opera." In fact, rehearsals are supposed to begin this week. We asked Riccardo if she's ever approached him. "I can not answer that!" he said, laughing. "I would do a special project for her. I respect her very much as an actress. She doesn't represent what is my world, but I would do something special for her. Because she is a great actress. She is a really great actress."
