Thank you I really like the song ttyl.

I had an inkling that it was a perhaps mockery of puritanical society and/or values but I wasn't quite certain. This is not to say that the dancers in question were inadequate in portraying the story-they were very fluid in their movements and clearly quite talented- I simply wasn't positive about the end and what the hat signified; except perhaps a change of character in one of the girls(?). :)
