ALL THAT GLITTERS: Balmain’s show on Thursday was a magnet for jewelry aficionados, with Aurélie Bidermann and Nadja Swarovski both spotted front row. Swarovski said the Austrian crystal firm’s role is growing beyond the jewelry world. Having created the backdrop for Adele’s performance at last weekend’s Oscars, Swarovski also just finished producing its first movie, a Julian Fellowes adaptation of “Romeo and Juliet” due out later this year. “It’s another natural role for Swarovski, evolving from our role in product placement, in costume design and set design, and eventually investing in creativity by supporting a movie,” she said. Also taking in the sparkle were Cher, Fergie and Tallulah Harlech.
