Greetings! I'm almost done with preparations for our upcoming family vacation and just realized I have no clue what the expected dress code would be for a matinee showing of Swan Lake by the Royal Ballet. I've already secured tickets and my daughter and I are over the moon excited, but we don't want to over dress and certainly don't want to under dress for the event. We've attended many ballets here in the United States (New York City Ballet, American Ballet Theatre, Mariinsky during their tours, etc) but I don't know if things are done differently at the Royal Opera House. Thank you so much for any guidance any of you wonderful London Travel Forum visitors could provide.
