Would definitely recommend Giselle (my favourite) if you liked Swan Lake. Also a couple Christmassy ones -Cinderella and the nut cracker (philistine to suggest but I prefer the traditional versions to the Matthew Bourne productions). Also a couple of Shakespeare ones - Romeo and Juliet, and, midsummer s night dream.
I have seen several balletsLa Fille Mal Garde, Copelia, Sleeping Beauty and The Nutcracker - My favourite Ballet by far is La Fille Mal Garde. It is a comedy ballet and I sat through it riveted to my seat. I really want to go and see it again.
I have never been so enthralled watching ballet before in my life (my previous favourite was 'I got rhythm' from Northern Ballet followed by this year's 'The Great Gatsby') & the music - just wow (only one piece I really didn't like the music for although the dancing was spectacular)
& then the company came out afterwards to talk to DD's dance school
