My ballet career was exactly one year long and ended because my mother refused to sew any more sequined costumes for me. Alas, I never got to dance in Swan Lake (but I was a cowgirl in "Rodeo Hoedown"), but I can admire their costumes from afar. Marc Jacobs showed his 2008 SS collection with loads of bejeweled fairy tale characters, but my favorite was definitely his swan choker.
