I've found out that the party I'm going to next weekend is fancy dress, on the theme of '60s free love' - so hippies and all that, basically. Can anyone suggest anyone in particular I can go as? I could do something generic but I'd prefer to actually be dressed as someone. My friend is going as Sun Ra!

Any suggestions? Please remember that 1) I am a lady
2) I want to look vaguely hot, and not like a twat.
