That happy grown up female feeling

I can't decide:

1. Totally outdated 1960s mentality toward womanhood?
2. 1960s feminist critique of outdated views of womanhood?
3. 1960s feminist reclamation of womanhood and the power of sexuality?
4. Clever critique on immature teenage views of womanhood?
5. It's just an fucking musical, get over it you crazy over-thinking-everything doctoral student.
6. All of the above.

God I love her outfit.
